In the game
The Boomers dream of raising the B-29 bomber that lies at the bottom of the lake, in the quest Volare!
The real place
The reservoir behind Hoover Dam. A real B-29 Superfortress crashed into it in 1948 and still lies on the lake bed.
Visiting
Rent a boat or kayak from one of the marinas; the B-29 wreck can only be visited on licensed dives.
