I have 4 migs on the apron waiting for their takeoff time as a "take-off" event [staggered 5-10-15-20 min apart]. I can't seem to get all 4 to show at the same time so they can be seen waiting on the apron to take off, thus being vulnerable to an air attack. They seem to appear 1 by 1 only, just when the previous plane has taken off 1 will appear. Can I get it to work so they can be seen waiting on the apron to take off, thus being vulnerable to an air attack?
