Sunbathers watch in shock as Russian Navy hovercraft plows onto beach Beachgoers heard a 'terrible roar' as the 550-ton Navy vessel hurtled toward a crowded shoreline in Mechnikovo, Kaliningrad. A massive vessel of war plowed onto a Russian beach in broad daylight, startling dozens of beachgoers who were just out to enjoy the sun. The 187-foot long military hovercraft glided onto a beach in Mechnikovo, Kaliningrad, as sunbathers took a break from tanning to gawk. Witnesses heard a "terrible roar" and saw "big waves," but overall appeared to remain calm, Metro reports. A woman holding a child walked slowly away from the scene, but turned back for a better look. That's when paratroopers stormed out of the 550-ton ship and ordered everyone and their towels off the beach.
