What was the ability of the Harrier jump jet aircraft?
Correct Answer: To take off vertically
The Harrier jump jet was a British-designed aircraft with the unique ability to take off and land vertically, without the need for a conventional runway.
Developed by Hawker Siddeley in the 1960s, it was used by the RAF and Royal Navy and famously served during the Falklands War (1982).
It was the world's first operational fixed-wing VTOL (Vertical Take-Off and Landing) jet.
