British Marines test out a jetpack in the open sea
British Royal Marines have been testing actual, real jetpacks by flying between speeding boats at sea.
Video shows a marine flying from a launch onto a larger Royal Navy vessel.
The jetpacks are developed by Gravity Industries, who claim they can fly at speeds of up to 80mph (128kmph) and climb to 12,000 feet (3,657 meters) – roughly equivalent to the highest mountains in Spain and New Zealand.
