I have a friend that tried to fly under the Coronado bridge. They crashed into San Diego Bay. Both drunk.
The interesting thing about this bridge is that because the Navy berths a large fleet south of the bridge (Bay entrance is North), the interior box girders are filled with foam so the structures will float if bombed.
It’s taller than all their fleet other than Aircraft carriers that are berthed on Coronado island north of the bridge (background in picture).
Speaking of B29s, have you seen the tragic story of the Kee Bird B29, that Darryl Greenamyer almost rescued in Greenland?
Sad story for the B29, a mechanic that died during the attempt, and all those who worked so hard to rescue it.
