I actually considered putting one of these in Vectors, as Alphasim made an Orlenok Ekranoplan awhile back, but I couldn't find a way to fit it into the story and have it make sense... not that anything in it did anyway. ;)
Good thing someone else took care of that for me! Got a laugh out of their attempts to traverse land with one, with mixed results. ;)
Cheers to Pebble for the link.
