I watch about this infamous "Gimli Glider" many times in Nat Geo channel Air Crash Investigations episode. Many says it's the miracle landing before Sully, which also safe landed. The Air Canada case in my opinion is pretty similar with Sully's case, both lost both engines and both glide down and landed safely, one on Gimli Airstrip and one on Hudson river, but Air Canada flight 143 started on much higher altitude (41,000 feet) which give the crew more time to think. The key part is the sideslip manuver by pilot Captain Pearson, to slow down the plane before landing. The papermodel is in 1:100 scale.
