... An interesting feature though is that, in a flight of 4, the -950 ac can be missing and already in the air.
More later as my son in town so real life stuff!
I get a few aircraft in the air for spawns where there are more aircraft than takeoff points in the runway objects file. For a sweep spawn with 6 fighters set to takeoff, two will appear above the runway while four occupy the standard takeoff points. In my BoB campaign, a larger flight of 8 or so Hurricanes will all spawn in the air above the airfield.
Here are the takeoff positions for aairbase1600.xdp. Probably one of Charlies. Note width=200, surface is concrete.
