The Lake Mead B-29

The account

In 1948 a B-29 Superfortress skimmed too low over a glassy Lake Mead on a secret high-altitude research flight, clipped the water at 230 mph, and sank, the crew all swam clear. For half a century no one knew exactly where. A dive team found her in 2001, remarkably whole, in the Overton Arm; the falling lake has since brought her from 200 feet up toward 100. She's on the National Register now, look, don't touch.

Leads, where the trail points now

• The site is documented at Overton Arm, Lake Mead, Nevada; the open questions now are access and what remains, not where it is.
• Lake Mead NRA (NPS), on the National Register, diving only under permitted, guided programs.
• What is there: A WWII Superfortress on a secret mission, intact on the lakebed.
