Short landing

It sounds like he slams the engines in reverse (thrust reversal) before the wheels touch the ground.

The Il-62 was the first long-range jet airliner to be put into service by several nations, and some retired examples have been converted into museums and other uses in countries such as the Czech Republic, Germany, Austria, Cuba and China (Thiel, 2001). The best known example was the Il-62 "DDR-SEG" from the former East German airline Interflug. On 23 October 1989, DDR-SEG was intentionally landed on a 900m short grass airfield of a hilltop Stölln/Rhinow in a potentially dangerous and dusty maneuver. Fire trucks and ambulance crews were positioned on hand for the landing but were not needed. The jet is used to commemorate the site of the fatal crash of Otto Lilienthal (1848–1896) at the Gollenberg hill. Nick-named "Lady Agnes"after Lilienthal's wife, it is now a museum with the fuselage divided between the Lilienthal collection and a popular wedding registry. Unknown source (Live Leak)
