I've flown on them in and out of both Kandahar and Bagram. The approach and departures are phenomenon, they seem almost vertical and makes the an us pucker
They have ability to open the cascade reversers in flight (they have cascade and bucket reversers on the engines). When they do that, it mimics the space shuttle re-entry, even sounds somewhat like the shuttle
For a test once they descended from 39,000 feet to 500 feet (AGL) in <3 minutes. (The test flight crew screwed up so we had to repeat the test the next flight as the geometry wasn't correct)
