Final answer:
The "angle of mercy" often refers to the Gimli Glider, a Boeing 767 that safely landed without fuel, resulting in no fatalities and minor injuries, and was retired in 2008.
Step-by-step explanation:
One aircraft that is often referred to as an "angel of mercy" is the Gimli Glider, the nickname given to an Air Canada Boeing 767 jet that ran out of fuel and safely glided to an emergency landing at Gimli Industrial Park Airport on July 23, 1983. This incident is a remarkable tale of pilots' skill and averted disaster. Adding to the aura of this plane's 'angelic' rescue was the fact that, despite the potential for catastrophe, there was no loss of life, and only minor injuries were associated with the emergency evacuation of the aircraft after landing. The Gimli Glider served until its retirement in 2008, a testament to its durability and the incredible story of its mercy glide.
