The idea is to have dog fights where you need to line up your aircraft with another, and if you get it right, it sets off a smoke display on the target aircraft.
I discovere ...[text shortened]... ot at night on a building over 500m away, although the spot is well over 1m in diameter by then.
I also have a couple laser pointers, red and green. The green one is pretty powerful but there are others a LOT more powerful, some blue one powerful enough to light a match.
So those lasers, the more powerful variety, would probably suffice for simulated dog fights. What kind of plane would these be going on? American jets? Russian?. It would seem you would need to be able to spot the laser at kilometer distance.
Here is one detector available for a couple hundred dollars US:

There would of course, have to be some engineering mods to use this in an automatic mode where the detector performs some job not meant to be used in the original model but that would just involve finding the output of the detector and tagging it with a wire and outputting that to whatever kind of interface you need, analog, using an A to D in a digital system and so forth. I don't see the actual detector specs for this device but there are probably others equal or more sensitive.
