"Many years ago I got to crawl through FiFi, thought it only cost me 10 bucks, was great"
Did it two years ago for FREE....well, actually I believe I paid like 5 bucks to get into the air museum in Odessa.
FiFi was in the hangar, having some repairs done (3 engines were either dismounted or in some state of repair), I got to check out the B-24, then wandered off.
No one around, (they were busy with the nose wheel on the B-24) so I crawled up and checked her out.
Was great, to actually be inside such a plane.
Was scared to death they were gonna throw me outta the museum if they found me, but I had waited 30 years to be so close to these machines. I figured if they did catch me, it was still worth it.
As an aside.....they had an I-16 there. TINIEST fighter craft I could imagine. More like one of those GeeBee air racers. A fella had to be brave to take to the skies in one of those little dinky birds, IMO.
