Meaning?
When the fight began, Iceman and Hollywood both flew together while Mav was on the carrier readying up for alert launch. Hollywood reports being shot down, thus giving Mav the go-ahead to launch and save Iceman. If all 6 MiG's were going after Iceman, don't you think they would've shot him down already BEFORE Maverick could even manage to enter the battle zone, even at supersonic speed?(That is, unless the fight was dangerously close to the ship where they launched off)
And how come the Tomcats weren't equipped with the long-range Phoenix missiles just in case the MiG's came within range of their radar coverage? I know it's supposed to relate to their training at Miramar, but even a set of those babies would send them scurrying back to land.
