This guy landed 81 kills in about 30 minutes.  
I dont fly f4f's but Im gessing its good for about 12 kills (give or take) for a great shot.  Proxies not with standing.  
Id say it takes at VERY LEAST 5 minutes to land and rearm even with a cv right off shore.  
With a far-better than average run of 18 kills it would take him 23 minutes just to land and rearm.  81 kills in 7 minutes?  Not unless he dropped a nuke on tank town!
