Example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lo during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,

New input case for you: Question: At what age did Gerry Anderson produce The Secret Service? Passage:The Investigator was Gerry Anderson's first puppet production since The Secret Service (1969), the last Supermarionation series to be made by his former company Century 21 Productions. Having gone on to make the live-action series UFO and The Protectors, neither of which were made specifically for children, Anderson wanted to create something new for the younger audience and devised The Investigator as the template for a new Supermarionation programme, intending to pitch it to American network NBC in the hope that it would commission a series. The pilot was planned by Anderson, his wife Sylvia and their long-time business partner Reg Hill. Written by Sylvia from a story by Shane Rimmer, it was funded by private venture capital and produced by off-the-shelf company Starkits between The Protectors and a planned second series of UFO (which was later made as ).
