Skiathos Airport
The 757 was still too fast and tried to vacate the runway via the nearest taxiway but the pilots didn` t manage to turn around in time and as a result they were standing in front of the grass next to the taxiway.

They decided to use the reversers to taxi backwards. These "powerbacks" are extremly rare and civil aircrafts usualy don` t do it.

Within the past twenty years I only saw two "powerbacks", performed by military aircrafts, a Casa 295 and a C-130 Hercules.

I know that Northwest was well known for powerbacks when they still used the Dc-9 but I have never seen a Boeing 757 going backwards without the assistance of a pushback truck.
