Quoted from DrJM:Does anybody knows why the PLANE of the pinball have a tail number of D-EAQV when in the film (third one) the plane have D-EKVY ???

"The actual plane used in the filming of Indiana Jones and the Last Crusade was a Belgian Stampe SV.4 biplane. Its actual registration is G-BHFG. The presence of a tailwheel and the flush wing tank separates it from a British De Havilland DH 82 Tiger Moth. Indiana Jones: The Ultimate Guide refers to the plane as a modified Buecher biplane, possibly meant to be a modified German Bücker Bü 131.
Originally, the film was going to include a second biplane, launched from the zeppelin, and flown by the World War One Ace and a Gestapo agent. These scenes were cut from the film but were left in the novelization and comic. The film, however, clearly shows the zeppelin carrying only one biplane at takeoff.
From Star Wars To Indiana Jones - The Best of the Lucasfilm Archives identifies the model used by the ILM team as "German biplane". Note that the model uses a different set of call letters: D-EAQV, and has a model more similar to the Gestapo agent than to Henry Jones, indicating that this was the model for the second biplane."
