Every inch of that airport and all runways are covered by video cameras, many of them. There should be no ambiguity here. Let's hope they release the footage.
Even if you want to do the 6' long at 900' (300 yards), that's only about 4/10ths of a degree across.
Those aren't things that are captured on camera well. These are angles that are similar to a 110' long airplane cruising at 38000' (that spec in the sky leaving a contrail).
