Ed: good to hear from you bro. I'll try the needle idea.
VonL et al.: I think I will make new hatches and see how they turn out compared to the kit plastic. I definitely will make a go at lighting the crew cabin. There are number of instrument panels that would lend themselves well to fiber optics.
I researched the seats a bit, and in 1/72nd scale, I think a good approximation would be ACES II seats, where the angle-of-attack sensors are removed and the cushions are red instead of sage green.
I do not belong to the accuracy-gestapo, but I want to make an effort.
(I view every model as an approximation, but that's another convesation.) ;)
Thanks a bunch for the advice, and keep it comin'! :)
