The Hendon Lancaster 137 not out

A few years ago, I drove down with the family to the RAF Museum at Hendon, just to the north of London. I made an immediate bee-line to the Bomber Command section to see their Avro Lancaster. Most of the aircraft here have their original coat of paint from World War II, so, to prevent it fading away completely under the onslaught of bright, harmful sunshine, the lighting is very subdued. That made it rather difficult for me to take photographs of a decent standard. Indeed, for the general view of the aircraft, I have had to use a photograph from the Internet. Here it is, with its capacity to carry up to 14,000 lbs of bombs into Nazi Germany:

HendonLancaster GOOGLE
Here is the front of this mighty bomber. Its huge black tyres are not far short of the height of a man. The yellow tips of the propellers are a safety feature and the yellow letter “S” is the aircraft’s squadron letter as “S-Sugar”:
P1320296XXX

This is the rear of the bomber. It has twin tails to give the mid-upper gunner a greater field of fire. You can see the door for the crew, which kept them well away from the four propellers, but it meant a very long and difficult crawl to the front of the aircraft. Its squadron letters are PO-S and its serial number is R5868:P1320297XXX

This particular plane is the oldest surviving Lancaster and the first RAF heavy bomber to complete 100 operations. It eventually went on to fly 137 sorties. R5868 was originally “Q-Queenie” with No. 83 Squadron at RAF Scampton and then became “S-Sugar” with No. 463 and No. 467 Squadrons of the Royal Australian Air Force at RAF Waddington. Its very last job came in May 1945, when it was used to transport liberated Allied prisoners of war back home to England.
The four Merlin engines have on them the names of the crew who received decorations. This is the starboard inner engine:
P1320283XXX

Here is another name, this time on the port inner engine. You can also see what looks to me to be an 8,000lb bomb underneath the enormous bomb-bay. Such a large bomb was made by merely bolting together two ordinary 4,000lb “Cookies” or Blockbuster bombs:
P1320285

I couldn’t resist showing you for a second time, in this second blogpost, the front of “S-Sugar”, which is adorned with the vain boast of Hermann Göring, “No enemy plane will fly over the Reich Territory”.

It is deliberately painted next to the symbols which represent the huge number of raids carried out over Germany by this one particular aircraft. All of the Avro Lancasters added together flew 156,000 missions over Europe as a whole and they dropped 608,612 tons of bombs on the Third Reich. So much for Hermann Müller and his pathetic promises, detailed in that previous post:

P1320286XXX

This is a “Grand Slam” bomb. It was designed by Barnes Wallis and weighed 22,000lb, ten tons, more or less, and the specially adapted Lancasters of 617 Squadron who carried it were at their physical limits:
P1320321

My Dad said their wings were shaped like giant crescents as they took off. When they were dropped, the bombs broke the sound barrier. At that time they must have been among the fastest objects made by Man. They penetrated deep underground and, when they exploded, they easily proved their nickname of the “Earthquake Bomb”. Unlike the majority of bombs dropped by the Allied Air Forces, they were always used on military sites such as U-Boat pens, gun-batteries or railway bridges.
Here is one being dropped by YZ-C of 617 Squadron:

I found two films about dropping a “Grand Slam” bomb. In both cases they are being used to destroy railway viaducts, in order to prevent the Nazis from moving troop reinforcements around their fast diminishing country. In this way, these spectacular bombs must have saved the lives of a lot of good men:

The Cadillac of the Skies

 

On August 17th, 1943 the Eighth Air Force had tried to eliminate the ball-bearing factories at Schweinfurt, deep inside the German heartland. Flying in daylight, and unescorted for the vast majority of the trip, the raid had been an audacious catastrophe. Some 230 bombers had taken part, and sixty of these were completely destroyed. As well as these sixty B-17s, a further 55-95 bombers were badly damaged. Many of these were too severely damaged ever to be repaired.

Living legends

The Eighth Air Force regained its composure, made good its losses in both men and aircraft, and, on October 14th 1943, they attacked again.  Flying in daylight, and unescorted for the vast majority of the trip, the raid was arguably a bigger disaster than the previous one. Of the 291 B-17s on the mission, 60 were shot down over enemy territory and another 17 damaged so severely that they had to be scrapped. A further 121 aircraft were damaged to a greater or lesser extent. These losses represented more than 26% of the attacking force.

The losses of aircrew were equally devastating. Some 650 well trained and skilful specialists were killed, which constituted some 22% of the 2,900 brave young airmen who went on the raid. The 306th Bomb Group lost 100 men, with 35 either killed in the air or died of wounds and 65 made Prisoners of War. The 305th Bomb Group lost 130 men, which was 87% of their complement.
General Henry H. “Hap” Arnold was later to state that the Black Thursday loss of American bombers in the Schweinfurt raid was “incidental”. Despite this callous dismissal of the lives of well over six hundred of his own men, further unescorted daylight bomber raids deep into Germany were immediately suspended until further notice. Cynics might well ask how many more B-17s  were left after the two disastrous attacks on Schweinfurt? Long distance bombing raids would only recommence in February 1944 with the advent of Operation Argument, a series of missions which would later be more commonly known as “Big Week”.

I live in Sherwood, a suburb in the north of the Nottingham conurbation in England. At the end of our street is “Hucknall Road” which leads the seven or so miles to the much smaller market town of Hucknall.

hucknall aerodromecccccccc

Strangely enough, Hucknall has a small grass airfield which is less than six miles from our street. Most days we can hear light planes making an enormous noise as they drone slowly overhead.

Hucknall RunwayxxxxxxDuring the course of April 1942, one man who frequently worked at Hucknall Aerodrome was to come up with an idea which would go a very long way indeed to winning the war in Western Europe. His name was Ronald W. Harker and he was usually known as “Ronnie”. Harker was the senior liaison test pilot with Rolls-Royce. Perhaps with Harker’s employer in their minds as an ulterior motive, the RAF had already invited the experienced test pilot to test fly the North American Mustang Mark 1, an American aircraft which was designed and built in the unbelievably short time of 117 days. This amazing feat was in response to a request by the British Purchasing Commission for an RAF fighter which would be an advance on the Spitfire.

The original North American Mustang was powered by an Allison V-1710 piston engine and Harker was quite impressed with the plane’s handling qualities. Its performance up to 20.000 feet or so was commendable, but any higher, and the aircraft quickly became rather disappointing. Harker concluded that the problem was the inadequate Allison engine which was too low-powered to exploit the plane’s advanced aerodynamic features including a much more fuel efficient laminar flow wing. This innovation cut down the amount of turbulence as the air passed over the wing and would eventually lead to almost phenomenally low fuel consumption.

Initially though, the new American fighter had an extremely unimpressive maximum range of only 400 miles, and when delivered to the RAF it was quickly relegated to Army co-operation and photographic work.
Ronnie Harker was employed by Rolls-Royce and was therefore presumably somewhat biased, but it was his suggestion to take out the Allison engine and to replace it with the Rolls-Royce Merlin 61, an act which was to transform a rather disappointing aircraft and to turn it into a war winner.
Despite a great deal of initial reluctance, mostly from the British Air Ministry, the first flight of the newly engined Mustang took place at Hucknall Airfield on October 13th 1942 with Captain R.T. Shepherd, the Rolls-Royce chief test pilot, at the controls. The Merlin-Mustang fighter’s performance was spectacular, particularly at high altitude. Thus the greatest fighter of the war was born and Harker acquired for the rest of his life the sobriquet of “the man who put the Merlin in the Mustang.” Harker also got a pay rise of a pound a week (just over one and a half dollars).

mustang cccccc

Some four hundred of the Merlin-Mustangs were ordered for the US Army Air Force as the P-51 and Great Britain wanted more than a thousand, although only 25 were eventually delivered to the RAF because Rolls-Royce’s own Merlin production was already allocated to Spitfires, Lancasters and Mosquitos. In the USA, however, North American, now almost overwhelmed by the orders to be filled, had no such problems, using Packard and Continental versions of the Rolls-Royce engine built under licence. Eventually, more than 15,000 aircraft were to be manufactured.

P-51_Mustang cccccccc
The P-51B carried just about the same amount of fuel as the P-47 Thunderbolt, but with its new Merlin engine “got 3.3 miles per gallon while the P-47 got less than 1.8.”. Brigadier General “Tommy” Hayes said that the Merlin-Mustang “had the three qualities you need most if you were going to escort bombers to Berlin – range, range and range.” The latter was extended even further by the carrying of two 512 gallon drop tanks which gave a maximum range of around 2,000 miles. In addition, the aircraft’s top speed increased from 390m.p.h. to 440m.p.h. and in the days after the war had finished there were to be many no doubt apocryphal tales of Mustangs which had exceeded the sound barrier in a steep or even vertical dive. In his memoirs, the P-51 ace Colonel Clarence E. “Bud” Anderson said that the Mustang “went like hell” because “the Merlin had great gobs of power and was equally at home high or low, thanks to its two-stage, two-speed supercharger.”

Mustang-Ferocious-Frankie-01 cvcc

This newly updated Mustang was, of course, exactly the aircraft that the beleaguered bomber crews in the B-17s of the Eighth Air Force had been waiting for. Now, with help of “our little friends” they could go about their business with considerably less apprehension than had previously been the case. The new aircraft is certainly said to have had an impact on Herr Reichsmarschall Göring who “when (he) saw the Mustangs escorting the American air armadas over the capital of the Reich is said to have realised that Germany had lost the war.”

little friends cccccc

The mechanism by which the Third Reich was, along with Göring himself, quite rightly consigned to the rubbish bin of History, was by no means a complex one. The Mustang pilots were quite simply encouraged to engage the Luftwaffe fighters in combat at every opportunity.  Given the quality of the new P-51, especially the P-51D with its superb all round visibility bubble canopy, the Americans duly shot down both the aging Bf109s and the newer Fw190s. Gradually over the months, the Mustangs killed off all the most experienced and most effective pilots in the Luftwaffe. Between January and April 1944, the Germans lost more than 1,000 fighter pilots, of which 28 had more than 30 kills and eight had more than 100. On one mission to Augsburg, much later in the war, Mustangs put a final full stop to the last and greatest German threat, namely the twin-engined fighter armed with multiple rockets. They destroyed 23 of the 77 that came up to oppose them.

At the same time, as part of the same process, it became increasingly difficult for the Luftwaffe to find calm skies where rookie pilots might practice. And in any case there was soon too great a shortage of fuel for these young replacements to waste on practice flights. The situation swiftly went from bad to worse, and the Mustangs, and many other Allied fighters, all began to enjoy enormous success against increasingly weak opponents. The Germans were never ever throughout the rest of the war to enjoy air superiority.

Allied bombers began by day and by night to operate with increasing impunity and to have an increasingly greater impact on the overall fighting capabilities of the Third Reich.

The situation is perhaps best summarised by a joke which remains as yet unverified on Wikipedia. It was supposedly told by Wehrmacht soldiers in the weeks after D-Day:

“If the plane in the sky is silver, it’s American, if it’s blue, it’s British, if it’s invisible, it’s ours.”
AeroWorks_Tuskegee_xxxxxxxxxx

“This all happened because of the Mustang, and the Mustang succeeded because of the Merlin.”

I cannot resist finishing my hymn of praise to the most effective fighter ever by quoting the episode in “Empire of the Sun”, when the “Cadillac of the Skies” makes its appearance, strangely not in Europe but in China. Enjoy.

“The Lancaster: Britain’s Flying Past”

Last night, I watched the superb BBC documentary “The Lancaster: Britain’s Flying Past”

The ranks of those who flew Lancasters with Bomber Command in the Second World War have, with the inevitable passage of time, thinned out somewhat, but the BBC has managed to put together the requisite crew of seven combat veterans. There were, therefore, a pilot, a flight engineer, a navigator, a bomb aimer, a wireless operator, a mid-upper gunner and a rear gunner…”tail-end Charlie”.
john sergesant
Every single man in Bomber Command was a proud volunteer. During the course of the war, they were to suffer 55,573 casualties from a total of 125,000 aircrew (a 44.4% death rate). The average bomber usually lasted for fewer than ten sorties. Life expectancy for crew members could be as low as two weeks, the same as a soldier in the Battle of the Somme in the First World War. Of every hundred airmen who joined Bomber Command, forty five were to be killed outright, six would be badly wounded, eight were captured by the enemy, and only forty survived physically unscathed. From the men who were serving in Bomber Command on September 3rd 1939, only 10% made it through to the end of the war some six years later.
There was no knighthood for Bomber Command’s leader  though, and no campaign medal for his “old lags”. In 1945, Roosevelt and Churchill had been asked by Stalin to destroy Dresden for him, and the two Western leaders were only too eager to demonstrate their ability to slaughter the enemy, be it German, or perhaps, even, one day, Russian. But when Bomber Command, as the best area bombers in the world, carried out this ghastly task, as they had been ordered to do , they then found themselves ostracised by those very same politicians, who now wanted to be popular as humanitarians, and to win elections after the end of the war.
It was eventually public subscription that finally paid for Bomber Command’s well-deserved memorial, fifty years or so too late, perhaps…

The “Lanc” was the greatest bomber ever made. It could fly at 300 m.p.h. and carry an enormous weight of bombs, with the more usual 4,000 pound “cookies” often bolted together to form either 8,000 or 12,000 pound “blockbuster”bombs. A Lancaster might carry hundreds of incendiaries, and some specially adapted aircraft could carry the 22,000 pound, ten ton “Grand Slam” bomb designed by Barnes Wallis.

What an enormous bomb bay….

The aircraft’s immense power came from four magicians, well, four Merlin engines to be more precise…

The Lancaster is a very large bomber; museums often struggle to fit them in, as here at Duxford

Best of all is the Lancaster in the RAF Museum at Hendon in north London (very easy to reach off the motorway)

Don’t miss the vain boast of Hermann Göring, painted on the nose of the bomber(with his name misspelt!).

The Reichsmarschall was also foolish enough to say that if any enemy plane did fly over the Reich, then , as the man in charge of the Luftwaffe, people could call him “Herr Müller”, a common Jewish name. Well, guess who had the last laugh?
Göring‘s medals too, are in the museum…

A couple of years ago, I really enjoyed visiting East Kirkby in Lincolnshire to see their Lancaster.  The aircraft does not fly but is taxied around the airfield every day.

What a beautiful machine, painted here as “Just Jane”, a fictional character in the wartime newspaper, the Daily Mirror.

The force of the engines being warmed up is amazing…

Then it sets off around the very large field…

Before returning, eventually, back to its rightful place…

It’s just such a pity that there are so few Avro Lancasters left for us all to enjoy!
