	Bomber Pilot
		You know it would be considered very very bad to make excuses to bring your bombs back again, unless it was a genuine excuse.
		The bomb didn't go off because it was very heavy metal, about 6 inches of solid metal, not like a thing called a "cookie" which is light metal which would go off if you looked at it.
		They'd been bombing and one of these things had dropped off and all that would be left was a hole in the ground.

	VERY HEAVY CONVENTIONAL AERIAL BOMBS
		The tail fins on the Tallboy were offset 5 degrees to spin stabilize the bomb in a clockwise direction and a small counter clockwise rotation was imparted as the bomb rolled off the support chains at the time of release.
		The bomb bay doors were removed and the roof of the bomb bay was remodeled from a flat deck to an inverted V shape to accommodate the oversized Grand Slam.
		At least one bomb with a T104 assembly was recovered from the hardpan at Edwards AFB after a test drop from 25,000 ft at 300 mph TAS for analysis of the angle of entry, depth of penetration and path through the ground.

	tallboy_bomb (Site not responding. Last check: 2007-10-06)
		Tallboys were used with great success against massive targets during the end phases of the war; targets which had been thought to be invulnerable to attack using conventional bombing techniques.
		Most large Allied World War II aircraft bombs had very thin skins to maximise the weight of explosive which a bomber could carry — this was an improvement on the early part of the war when the actual HE content of British bomb designs was low.
		The weight of the Tallboy (approximately 12,000 lb.) and the high altitude required of the bombing aircraft meant that the Lancaster bombers used had to be specially adapted.

		Fuzing is characterized by the means by which the bomb is armed and the parameter that causes the fuze to detonate the bomb.
		Bombs were classified by their CWR (Charge-to-Weight-Ratio) the percentage of explosive compared to the gross weight of the weapon.
		The Grand Slam (Earthquake) bomb was of the same design as the Tallboy but larger and heavier weighing 22,000 lb (9972 kg.) The Grand Slam was first used on March 14, 1945 when a force of Lancaster bombers led by Royal Air Force Squadron Leader C.C. Calder attacked the Bielefeld railway viaduct destroying two spans.

	Grand Slam bomb - Wikipedia, the free encyclopedia
		The Grand Slam bomb was twice the weight of his previous large bomb, the Tallboy; both weapons were intended for use against large and protected buildings, and structures against which smaller bombs would be ineffective.
		The new design was highly aerodynamic, with a long tail incorporating offset fins, causing it to spin as it fell and stabilizing it, much as the spin imparted by the rifling of a gun barrel increases the accuracy of a bullet.
		The hardened steel bomb casing was cast in one piece in a sand mould using a concrete core.

	Tallboy Bomb
		It was ballistically perfect and in consequence had a very high terminal velocity, variously estimated at 3,600 and 3,700 feet a second, which was, of course, a good deal faster than sound so that, as with the V-2 rocket, the noise of its fall would be heard after that of the explosion.

	NLS - The Tallboy Bomb
		Known as the "Tallboy," there was no aircraft in the foreseeable future that could carry it so the design was put on hold.
		Released from the optimum height of 18,000 feet the bomb took 37 seconds to reach the ground, impacting with a speed of 750 miles per hour.
		During the night of June 8, 1944 the first Tallboy was dropped, causing extensive damage to the Saumur Railway Tunnel, preventing enemy reinforcements including tank units from reaching the beaches of Normandy.

	Big & Bouncy - the special weapons of Sir Barnes Wallis
		Tallboy's sleek shape enabled it to gain as much speed as possible during its fall, giving maximum penetration into the ground which was essential to maximise the earthquake effect.
		Tallboy was 21' in length, with a diameter of 3'8" overall (the bomb body itself was 10'4" long and 3'2" in diameter).
		Uniquely on this raid, the Tallboys were dropped at low level for accurate positioning; use of Upkeep again would have been more appropriate, but the Lancasters had long been returned to normal specification and there was not time to re-modify aircraft and train the new crews for delivery of the weapon.

	FlightSim.Com Review: The Dam Busters
		The scientist behind the now famous "bouncing bomb" was Barnes Wallis, already designer of several notable aircraft including the R100 airship (competitor to the ill-fated R101), long-range Wellesley and the Wellington bomber which distinguished itself early in the war.
		Two versions of the Upkeep Lancaster are included - one with a rotating bomb, and one with a non-rotating bomb (rotating the bomb enabled it to bounce further, but the Sorpe Dam was attacked along its length and the bomb was not to bounce).
		the bomb does appear to produce a series of splashes as it bounces across the surface, although the bomb itself is invisible after the first splash.

	AVSIM Commercial Combat Add-on Review: Dam Busters
		Thus, instead of trying to bomb all the widely dispersed war factories in Germany, it would be more economic and effective to attempt to destroy something of common need to all of them, such as raw material or power.
		The bomb aimer then used a "piece of wood and two nails" held at arms length to line up the two turrets of the dam to know at what distance from the dam face to release the bomb.
		The variety of weapons that are included with this sim are the Wallis "bouncing bomb" (which was actually a mine), the 12,000 lb "Blockbuster" bomb and the high altitude 12,000 lb "Tallboy" bomb.

	News - History in the Making - Renowned carpenter commissioned to replicate earthquake bomb
		Originally the Tallboy’s hardened steel case had a thickness of four inches of steel in the nose, but in order to transport the replica to the museum for display, Morel opted for lighter weight aluminum and wood.
		The Tallboy was the brainchild of Wellington Bomber designer Barnes Wallis in 1940, but due to the bomb’s envisioned weight of 20,000 pounds there was no aircraft to carry it.
		During the night of June 8, 1944 the first Tallboy was dropped causing extensive damage to the Saumur Railway Tunnel and preventing the enemy reinforcements, including tanks units, from reaching the beaches the Normandy, but its most spectacular success was the sinking of the Turpitz.

	::Barnes Wallis::
		Barnes Wallis is most associated with the Dambuster raid of 1943 when the legendary 'bouncing bomb' that Wallis developed destroyed several of the dams in the Ruhr.
		The bomb needed to be dropped at an exceptionally low height so that it hit a dam, did not explode but sank into the water.
		Wallis also invented the 'Tallboy' bomb that was used to penetrate the U-boat pens on the west coast of France.

		It weighed five tons and, carried by the Avro Lancaster bomber, was effective against concrete structures against which earlier, smaller bombs had proved ineffective.
		The size of aerial bombs available up to this time, and the difficulties in accurately hitting targets meant that bombing raids against any massive or protected structures had been a pointless.

	B-52's: Could they safely carry WWII Tallboy/Grand Slam bombs into OBL's caves? (Site not responding. Last check: 2007-10-06)
		Obviously there are problems to be resolved, but bomb computers can be re-programmed, flight characteristics of the bomb checked by drops of dummy weapons at Edwards AFB (to match th erocks, elevation, temperature and climate/winds of winter in Afghanistan as closely as required.
		It seems they can add their historical innovations: like radar, the dam-buster bombs, sonar, radar navigation, code-breaking, etc. to the war effort by building enough Tallboy bomb casings to destroy the AREA near the suspected caves to this war on terrorism.
		On the destructive effects of Tallboy versus bunker-busters, the shock wave of a fully camufletted 12,000 lb bomb is inevitably much greater than a 2-4,000 lb bomb.

	Avro Lancaster
		With a wingspan of over 100 feet, the Lancaster was also the only British aircraft with the capacity to carry the 12,000-pound 'Tallboy' bomb and the 22,000-pound 'Grand Slam' bomb — the heaviest bomb-load lifted by any bomber of World War II.
		The "Lanc" — as it was called — is also known for its daring and precise bombing raids on the Moehne and Eder dams in 1943 and in the sinking of the Tirpitz, a German battleship, in a well-defended Norwegian fjord.
		With fighters unable to escort the large aircraft on its long missions, it was heavily armed with nose, mid-upper and tail turret guns — and didn't give much room for the seven-member crew.

		Therefore the next mission for the crew was the V1 flying bomb storage depot at Creil, France, it was attacked and bombed on the 2nd July 1944.
		As a last resort when the launch sites had been bombed, the Luftwaffe decided to launch V1s from Heinkel bombers on targets in England, right up to 6 weeks before the end of the war over 1,000 were launched in this fashion, only when the Luftwaffe was finally defeated would this menace be stopped.
		After the initial 9th August attack, a succession of bombing raids were carried out on the U-Boat Pens at Brest, on the 12th, 13th, 14th August 1944, using 6 tonne “Tallboy” bombs, and 10 tonne “Grand Slam”; bombs.

		The Grand Slam (Earthquake) bomb was a very large bomb developed by the British aeronautical engineer Barnes Wallis in late 1944.
		The Lancaster was primarily a night-time bomber; unlike the Halifax, it was not used during the war for other duties than bombing.
		Initially the heaviest bombs carried were 4,000 lb (1,818 kg) or for special targets the 21 feet (6.4 m) long 12,000 lb (5,448 kg) 'Tall Boy'.

		These weapons were later revealed to be the “V-1 Buzz bomb,” a radio controlled flying bomb, the “V-2 Rocket” and a long range high powered gun with explosive shells, all aimed at London.
		To counter this threat the British developed the 20,000 pound “Tallboy bomb” for dropping on submarine pens and the launch sites for the V-1, V-2 and the long range guns, on the coast across the channel from England.
		Targets selected were invulnerable to conventional bombs because of thick reinforced concrete emplacements.
