How The C-17 Globemaster Drops 25,000 Feet In 2 Minutes Using Inflight Reverse Thrust

Simple Flying

The Boeing C-17 Globemaster III of the United States Air Force has a rare modification that allows it to do a unique feat in the world of aviation. The enormous tactical quadjet can switch to reverse thrust on all four of its Pratt & Whitney turbofan engines from high altitude and drop 25,000 feet down to ‘the deck’ on a tactical descent into a combat zone to make deliveries to troops on the ground. This unique ability allows it to stay at high altitude, where it is safe from many anti-aircraft threats until the very last moment, and then pass through the hazardous low-level as quickly as possible.
