Nice film!
The lead angle for a snap shot can be pretty significant. Here's an idea of the problem.
The yellow circle represents the nominal lead required for a 90 degree snap shot. I assumed fighter speeds to be the same (250KTAS), and an average muzzle velocity of 2500 ft/sec. The range is ~1000'.
The red arrow represents what the lead would be if you were in-plane with the target...clearly well out of sight!
Sorry about the ball...!!
