Very informative video from the Curious Droid channel on YouTube on “The Caspian Sea Monster” = USSR giant ground effect vehicle.

Paul Shillito’s Curious Droid channel has a ton of Aerospace content.

In Oshkosh 03′ I got to see a Lippisch single seat Wing in Ground Effect WIG vehicle at the hangers at the pioneer airport. It’s still likely on the EAA grounds
