Its a cool idea but for the current setup IMO it wouod be pointless to add these aircraft...Who's going to wait around 10,20,50 minutes in the main arena, or AVA for that matter for a rescue plane to scoop you up when you have unlimited lives, and can tower up and run another sortie...
That said, this may not be a bad idea for COMBAT THEATER, or even SCENARIO's where # of lives are limited..... I'd like to see something like this, especially for CT, but until that is released, I just dont see the point of adding it to the current setup
