Where, in Virginia? I'm in Richmond.

I have the plans. I rattled Markham's cage in 1981, after he'd
been out of the business for a while -- or so it seemed at the
time.

I once worked with hot plastic like that, in shop class in the 7th
grade. The experience left me feeling the same way you feel
about it.
I sketched out a slightly different idea for the canopy. Starting
with old airplanes, I imagined the canopy of the XP-31 replacing
the bubble. That would require heating and bending the plastic.
So I tried the canopy of the P-40 as a model, but changed it so
there were no curves at all.
