Well if it was radar from Vance where the pilots were from then maybe ... depends if it was terminal radar or search radar - or height finding ... then too, how far away is Vance from the stadium ... lots of factors there ... too low and they wouldn’t show up on the screen ...I think the pilots would have to fess up ...

I agree. They mentioned that there was video taken.Maybe they can judge the height and distance of the plane from the video.

then too, how far away is Vance from the stadium

Vance AFB is in Oklahoma. Kinnick Stadium is in Iowa.

I.e., roughly 700 miles.
