In Britain, the Royal Navy tested the 'jetpack' ( Technology News )

The Royal Navy tested the jet pack produced by Gravity Industries, UK-based jet pack developer. It is stated that the jet rocket provides the user with the opportunity to fly with a total of 5 mini rockets, in their hands and on the back, and has a speed capacity of 88.51 kilometers per hour. Navy officials successfully landed HMS Tamar, the Royal Navy's Batch 2 River-class offshore patrol ship, with a jetpack during the 8-minute flight test.
