Visible crew/equipment: When Kobayashi and Edie are meeting, what appears to be a boom mic is visible above Keaton's head when the group is seen through the window.
Visible crew/equipment: When Verbal drops the Zippo lighter in the police office, Chazz Palminteri leans down to pick it up. When he leans down out of frame, there are 2 "C-stands" visible in the background. These shiny, adjustable stands are general-purpose utility holders on a movie set, used to position lights and light control material for a setup (i.e. flags, scrims, diffusion, etc).
Suggested correction: It's for effect to show they were hanging out around the airport for more than a bit.
There's no evidence this was meant to be a montage scene of various planes. The cuts they did have in the first angle were of the same plane getting closer to build suspense. Same for the other angle. Plus, there's no scenes or shots of "them" waiting.
