The Gang Tries to Serve a Subpoena - S4-E2
Continuity mistake: Luca and party are about to board a green private jet. Moments later when they take off, the shot shows the forward underside of a white plane. At first I thought that maybe it was white on the underside, but the nose wheel well doors are indeed green, and the takeoff picture shows an airplane with white nose wheel doors. (00:19:40)
