I've built a few jet aircraft to carry rocket planes and ACLM's up to be launched. I put either command pods or command chips in each of the two aircraft. The launching aircraft pod/chip is set as primary and the "cargo" aircraft pod/chip is secondary. Once in flight, I launch the "cargo" aircraft using an activation group on the launching aircraft and then quickly hit a bracket key to switch to the "cargo" aircraft. I start the launched aircraft's engine and it scoots away under my control. What I've found is that if I want to go back to the launching aircraft and land it, hitting bracket keys do not send me back. It seems that once I take control of launched aircraft, I can't go back to the other aircraft. Is that just part of the program or am I missing something?
Its because the second craft is getting too far away from the first one and its not being rendered anymore so you have to go to the map screen to take control of it.
