I recently came across the video below on YouTube of a Royal Canadian Air Force Boeing C-17 on departure from Leeds Bradford Airport last May. I was amused by the cheerful waving of the soldier to the crowd while the aircraft is taxiing to the approach of the runway. It seems to lift very gracefully into the air for such a large aircraft.
The official Canadian designation for the aircraft is CC-177 Globemaster III.
They joined the RCAF fleet in July 2007 to perform military and humanitarian missions for which leased An-124 Ruslan aircraft from Russia had previously been used.
The aircraft featured in the video is registration #177703 which was the third of the original four ordered from Boeing. It is based at CFB Trenton. A fifth aircraft was delivered in 2015.
