29 April 1945: With the defeat of Nazi Germany imminent, millions of Dutch citizens were still under the control of the occupying German army. Food was very scarce. The Allies tried to negotiate a cease fire so that American and British airplanes could fly into The Netherlands and drop food to the people.
The truce had not yet been agreed to by Germany, but on 29 April, Operations Manna and Chowhound began.
The first night, to test the feasibility of the project, two Royal Air Force Avro Lancaster four-engine long range heavy bombers of No. 101 Squadron—Bad Penny, crewed by Canadians, and a second ship flown by an Australian crew—were loaded with food at RAF Ludford Magna and flew into The Netherlands at barely 50 feet (15 meters) above the ground.
To drop the food they simply opened the bomb bay doors and the bags and packages fell to the starving people below.

With Flight Sergeant Robert Fairful Upcott, D.F.M., Royal Canadian Air Force, [service number R187858] leading with Bad Penny, the two Lancasters ¹ dropped their food on the Racetrack Duindigt at Wassernaar, near The Hague, then returned along the same corridor they had flown on the way in. At 2:00 p.m. that afternoon, another 200 Lancasters followed.

Over the next ten days, approximately 11,000 tons (9,979 Metric tons) of food were dropped by Royal Air Force Lancasters and U.S. Army Air Force B-17 Flying Fortress bombers.

Friday, 5 April 1968: Flight Lieutenant Alan Richard Pollock, No. 1 Squadron, Royal Air Force, based at RAF West Raynham, southwest of Fakenham, Norfolk, was leading a flight of four Hawker Hunter FGA.9 close air support fighters. Pollock described the weather:
“Over London the weather was still one of those rare perfect 8/8 Gordon’s crystal, gin clear days when all the colours shout out brightly.”
Pollock broke away from the formation and flew toward London.
FLIGHT International reported:
Hunter to Tower—Under
An RAF Hunter few through the Tower Bridge, London, in a down-river direction just after noon last Friday, April 5. The Hunter, carrying underwing tanks, was glimpsed momentarily from Flight‘s offices in a descending, mushing turn until lost to sight behind United Africa House. Previous flights through Tower Bridge—never in a jet, and never so fast—have invariably been made in an up-river direction.
The MoD was investigating as we closed for press; the supposition was that the aircraft was an FGA.9 of 1 or 54 Squadrons, which comprise the close-support wing at RAF West Raynham. The station refused comment, but flying was taking place that day. Visibility was excellent. Some authorities attributed the incident to widespread resentment that the RAF had been deprived of a ceremonial fly-past on the 50th anniversary day, April 1. The Red Arrows were expecting to make this fly-past last month, but permission was presumably denied. A Ministry of Defence spokesman to whom we were referred at press time by the duty officer at RAF West Raynham, was not then able to reveal the name of the pilot.

. . . and the following week:
The Man Who Shot the Bridge
The RAF pilot who flew a Hunter FGA.9 through Tower Bridge, London, on April 5 was no youthful prankster but a senior flight commander of 1 Sqn, RAF West Raynham, an Old Cranwellian, and the father of four children.
He was Flt Lt Alan Richard Pollock, aged 32. He was named on Sunday, April 7, by MoD (Air) too late, owing to Easter press schedules, for mention in our last week’s story. Flt Lt Pollock was placed under close arrest on April 5 and released into open arrest on April 7. A board of inquiry was convened at West Raynham on April 8. An all-party motion signed by six MPs [Members of Parliament] was tabled in the Commons in his support but was ruled unacceptable.
Whatever their views on the responsibility and possible consequences of flying a jet fighter through the 200ft-wide, 110ft-deep aperture framed by the towers, the bascules and the upper span of Tower Bridge, there is unanimity among pilots that it was a handsome piece of flying.
Flt Lt Pollock was the first pilot to fly through the bridge in a downstream direction, following the gentle sinuousities of King’s Reach from the Waterloo Bend—and passing over Blackfriars’ two bridges (road and rail), Southwark Bridge, Cannon Street rail bridge, and London Bridge. After clearing the last he probably had little more than five seconds to align himself with the eye of the needle presented by Tower Bridge, retaining until the last fraction of a second the option of pulling up had he found the opening partly obstructed by abnormally high vehicles, by hanging cradles or by the bascules opening.
It has been reported that Flt Lt Pollock peeled off from a formation returning from RAF Tangmere, where he had led four Hunters on display duties. This might have accounted for his choice of direction. The absence of pre-placed photographers, who always seem to have been around on previous Tower Bridge buzzings, seems to rule out premeditation. Another explanation of why he preferred the crane-lined Upper Pool downstream of Tower Bridge for his climb-out when all previous pilots have used it for the run in may have been to avoid climbing through the flight levels occupied by airliners on the approach to Heathrow had he made a westerly climb-out. He turned to port over the City.
The RAF and civil authorities were tussling last week about whether Flt Lt Pollock should be court-martialled or tried in a civil court. His one-man fly-past was construed in and outside the RAF as an expression of resentment felt by many in the Service—including those now responsible for deciding his punishment—of the way the Royal Air Force is being treated by the Government. It may be that the last straw was the cancellation of the 50th anniversary fly-past over the capital on April 1. A fly-past planned in conjunction with the Lancaster House dinner with the Queen was cancelled at the last moment as “inappropriate.” A mid-day fly-past, seen by the maximum number of Londoners and visitors, would have been most “appropriate” on this occasion.
Attitudes to the Tower Bridge exploit of past and present members of the RAF whom we have questioned vary from the very strongly censorious to the frankly admiring; but an unvarying theme was that some RAF protest was called for, without infringing flying discipline.

The Royal Air Force did not court-martial Flight Lieutenant Pollack. A medical board discharged him from the service. The Ministry of Defence announced that Pollack had been hospitalized with pneumonia, and that, “. . . if he were brought to trial it would probably have a damaging effect on his health, both immediately and in the long term.”
An oral history recording with Alan Pollack (32 minutes, 20 seconds) is available at the Imperial War Museum:
This was not the first time an airplane had flown through Tower Bridge. On 10 August 1912, Frank McLean (later, Lieutenant Colonel Sir Francis Kennedy McLean, A.F.C.) flew his modified Short S.33 float plane, and, according to his obituary in The Times, 12 August 1955, “. . . created a record by flying up the Thames in a seaplane, passing between the upper and lower parts of Tower Bridge and under London Bridge without touching the water.”

Alan Pollock was flying a Hawker Hunter FGA.9, XF442, c/n S4/U/3318. It had been converted from a Hunter F.6 interceptor. The Hunter was a single-seat, single-engine, swept-wing jet fighter, which first entered service with the Royal Air Force in 1954. The FGA.9 ground attack variant was based on the Hunter F.6 interceptor.

The FGA.9 was 33 feet, 8 inches (10.262 meters) long with a wingspan of 45 feet, 10½ inches (13.983 meters) and height of 13 feet, 2 inches (4.013 meters). The wing area was 340 square feet (31.6 square meters). The wings were swept back 40° at ¼-chord, and had an angle of incidence of 1½°. There is noticeable anhedral. The FGA.9 had and empty weight of 13,010 pounds (5,901 kilograms) and maximum takeoff weight of 18,000 pounds (8,165 kilograms).
The FGA.9 was powered by a single Rolls-Royce RA.28 Avon 207 engine. This was a single-shaft axial-flow turbojet with a 15-stage compressor and 2-stage turbine. The RA.28 was 10 feet, 3.0 inches (3.124 meters) long, 3 feet, 5.5 inches (1.054 meters) in diameter, and weighed 2,869 pounds (1,301 kilograms). It was rated at 10,050 pounds of thrust (44.7 Kilonewtons).

The Hunter FGA.9 had a maximum speed of 702 miles per hour at 15,000 feet (4,572 meters)—0.97 Mach—and maximum range of 1,850 miles (2,977 kilometers) with external fuel tanks.
The basic armament of the Hunter were four 30 mm ADEN autocannon installed in a removable gun pack, along with 150 rounds of ammunition per gun. The ADEN was a gas-operated revolver cannon, capable of firing 1,200–1,400 rounds per minute. The FGA.9 could also carry a 1,000 pounds (454 kilograms) bomb under each wing, twenty-four 3-inch rockets, or two rocket pods with thirty-seven 2-inch rockets, each, for ground attack.
Hawker produced 144 of the Hunter FGA.9 ground attack variant, with 12 modified from F.6 interceptors. Most of Hawker’s foreign sales were based on the FGA.9.
Hawker Hunter FGA.9 XF442 was transferred to the Fuerza Aérea de Chile, 24 April 1982, and assigned identification number J-742. It crashed near Antofagasta, in northern Chile, 20 May 1982.
Alan Pollock was recently interviewed for the Daily Mail:
The Royal Air Force and Women’s Royal Air Force were founded 1 April 1918, by combining the Royal Flying Corps and Royal Naval Air Service. A very Happy Anniversary to our Cousins across the Atlantic!
19 March 1945: Modified Avro Lancaster B Mk.I Special heavy bombers of No. 617 Squadron, Royal Air Force, attacked the railway viaduct at Arnsberg, Germany, using the 22,000 pound (9,979 kilogram) Grand Slam earth-penetrating bomb. The bomb had been first used just days before, 14 March, against another railway viaduct.
The Grand Slam was the largest and heaviest aerial bomb used during World War II. It was designed by aircraft engineer Barnes Neville Wallis, and was scaled up from his earlier, smaller “Tallboy.” (Wallis also designed the “Upkeep” Special Mine used to attack hydroelectric dams in the Ruhr Valley in 1943.)
Wallis’ idea was that a very heavy, supersonic bomb could penetrate deep into the earth and detonate, causing an “earthquake” which could destroy nearby heavily protected targets.
Tall Boy and Grand Slam Deep Penetration Bombs (British Explosive Ordnance, Part 1, Chapter 7)
The Grand Slam bomb (officially, “Bomb, D.P., 22,000-lb., Mk I”) was 25 feet, 5 inches (7.747 meters) long and had a maximum diameter of 3 feet, 10 inches (1.168 meters). When fully loaded with the explosive material, Torpex, the bomb weighed 22,400 pounds (10,160 kilograms).

The bomb case was cast of steel at the Clyde Alloy and Steel Company, Glasgow, Scotland, then, after several days of cooling, machined to its precise shape. The casing made up approximately 60% of the bomb’s total weight. At the nose, the casing had a wall thickness of 7.75 inches (19.685 centimeters).
The bomb case was filled with approximately 9,200 pounds (4,173 kilograms) of molten Torpex, with a 1 inch (2.54 centimeters) topping of TNT. Torpex was an explosive designed for torpedo warheads and depth charges. It was made up of approximately equal quantities of two other explosives, Research Department Formula X (RDX), 42%, and trinitrotoluol (TNT), 40%, mixed with 18% powdered aluminum and wax. The resulting combination was approximately 1.4 times more powerful than TNT alone. About one month was required for the explosive to cool after being poured into the bomb case.
Because of its size and weight, the only Allied bomber capable of carrying the Grand Slam was a specially modified Avro Lancaster B.I Special, flown by No. 617 Squadron, Royal Air Force, “The Dambusters.”

Wallis intended for the Grand Slam to be dropped from very high altitudes so that during its fall, it would go supersonic. The bomb had large fins that were offset 5° to the right of the centerline to cause it to rotate for stability. However, the bombers could not carry it to the planned release altitude, and it was typically dropped from approximately 9,000 feet (2,743 meters). Its very sleek design did allow it to come close to the speed of sound, however, and its stability made it a very accurate weapon. The bomb was capable of penetrating 20-foot-thick (6 meters) reinforced concrete roofs of submarine bases. ¹
