I remember the noisy buggers coming into Faslane oh so long ago. Just dredged this up whilst wasting a bit of time....not much info about the RN side of the tests/trials though. We invented the things. Would have thought there would be an "Old Pussers Hovercrafters Association"?
Probably is....elitists! :ufo: (Well the smiley looks a bit "Hovercraft'ish")
