Wyvern Differences
IIICorps:
This pic of the Wyvern here is different from the one in the EF thread-drift: the exhaust isn't under the left side of the cockpit. It appears to be the long horizontal slot on the left side of the engine....which seems odd, as it doesn't look like it has any high-temperature metal there to cope with the exhaust.
The Gannett: Looks like an SBD and a Hudson had a bastard love-child.
But then, I flew the OV-10, and a few of us said it looked like an A-10 and a helicopter had a love-child.
The Skyshark: I wonder why Douglas used that hideous canopy instead of the original bubble?
