Why did nobody bump into the Klingon ship...
...when it was parked invisible in the public park? The weather wasn't bad, dozens if not hundreds of people should have walked across the grass during the time it was there and got a sore nose.
What would a 1986 human do in that situation? Freak out and report it most likely... Scully and Mulder would have been called out within hours, the scene taped off and be swarming with Feds. But not one person apparently did so. Did I miss something or is that a bit of a plot hole?
