Ok Trevor, I remember now...(I suffer from CRS) I'll see you at NJHMA this year I presume...since you're near Trenton, I'll also be headed for Harrisburg on the 27th.
Al, I envisioned the Betty as having been pushed by the Marine's best friend in the Pacific...a SeaBee bulldozer!!!
I'm scratchbuilding one now...the way I see it, the weak point in the Betty's fuselage is at the hinomaru, since there was a large circular hatch in that location. With that hatch removed, and the airplane forced in a direction against it's will, it probably would have broke right about there...or, I can say an artillery shell did it...there's lots of photos of severed tails in Donald Thorpe's Japanese Naval Aircraft Camo and Markings of WW2 book, although none admittedly are Bettys...without the tail broken off, it kinda looked like it didn't belong there...it's hard to make an airplane that small look derelict without breaking something. :-)
