Sure the Peggy is nice and all......
But the Betty sure did have a long, important, operational history in the war.  
You might say it's a "flying zippo" or a "one shot lighter," but aside from poorly constructed fuel tanks, it was built pretty well.  And I might call my 24's the same thing.  Fast and maneuverable, it could carry out it's bombing and turn before fighters had a chance to intercept...  Then again, you might want it for a torpedo run.

~~~~Must be manned at takeoff, no joining.  Literally a kamikaze run.  Perks scored Attacker towards Bomber.  Ohka ord 12k (2,650 lb).  Fly it same as any aircraft.... More or less.    Should be perked, not much, but a little!
Ohka is a rocket engine, manned, weapon.
