I was half right, knew what a B-29 was/is, I just didn't equate the two. I was thinking anti-gravity flight in an old airplane. That would be one helluva ride, but I'm pretty sure an old B-29 wouldn't be capable of such a flight.
Looks like a cool dive. A frined of mine got certified diving 15r yrs ago and keeps getting on me(and wife) to get certtified. He lives for diving now.
About a million years ago I finished a similar depth dive on the Thunderbolt off of Marathon Key, FL. I much prefer a reef dive than a wreck dive, but I understand that others prefer the opposite. Diving is a bunch of fun and I hope to do it again soon...............although that's unlikely.
