00:00A 150-ton Navy hovercraft crushes jagged rocks while sliding across deadly swamp terrain at
00:05terrifying speeds. How does a massive warship glide across dry dirt without tearing its metal
00:11hull to pieces? Common Sense says rigid metal walls trap the air, but solid barriers smash
00:17instantly against boulders. Flexible elastomer membranes seal pressurized gas beneath hulls,
00:23eliminating surface friction during transit across coastal mudflats.
