After McCloud reports his gun as missing to Teri Garr, Ravik's plane from Rome is shown landing. First as it shown from a distance as it is about to touch down, it is show with tricycle landing gear (wheels under each wing and nose gear). Then, as it actually does touch down the view is from under the aircraft, two pairs of landing gear directly under the fuselage (a pair of of landing gear towards the nose, and another pair of landing gear further back under the fuselage). Then, lastly, as the aircraft approaches the boarding gate, it has tricycle gear again.
An earlier commenter posted that Cesare Cimarosa's (Jay Novello) name was mis-spelled as "Cecero." While "Cecero" IS mis-spelled, it didn't refer to Cimarosa, an old man dying in his bed in Rome. It referred to Perry Cicero (Nehemiah Persoff), the collectibles dealer and fence in New York City who was moving the stolen Saracen Horse.
Cesare Cimarosa's first name is misspelled 'Cecero' in a newspaper headline shown on screen.
