I'm trying to figure out how long the aircraft is, that is hiding behind the call box. I can see its top rear fin and its exhaust trail, so I know it's back there. See video: Time = 00:25.

The first triangle is formed by the camera at one corner and a call box of length 2.5 ft., as the opposite side. There is a distance of 28.8 ft between them.
The second triangle is formed be the same camera at one corner and the aircraft of length "X", as the opposite side. The distance between them is 691.2 ft.
I know its suppose to be a ratio between 2.5 ft. is to 28.8 ft, as "X" is to 691.2 ft. I also know the aircraft will be a little smaller than the answer since it easily fits behind the call box.
Can you help me solve for "X", the aircraft length ?

The distances were scaled from a satellite image of the pentagon, where each of the five walls is known to be 921.6 ft in length.

The call box measurement was scaled from the video, where the patrol car is know to be aprox. 16.5 ft in length.

Not sure what you mean but as for 2.5/28.8=x/691.2
2.5*691.2/28.8=x
looks like 60 to me
