I can see how one might do that many kills in a GV, with the way a GV can be resupplied, is possible to rack up those kinds of kills in that time span, as for the flying , he probably got hit by the score bug , ( someone up above posted bout it ),
no possible way to score those kinds of kills in that amount of time, and still take out nearly 2 minutes to land rearm and take off and fly back to the fight......
Please note , I have not accused anyone of anything ( wanted to make that clear )
