Yeah, that was pretty funny. Crippled by a single biplane and "most powerful afloat" are mutually exclusive statements.
The F4F-4s they used in the Guadalcanal episode were some wierd bash of parts of an F4F-4, and parts of an FM-2 (and no, it wasn't an FM-1, either

)
I also noticed the control surfaces don;t move. It would have been better filmed using Il-2, frankly.
