Well done . Iqaluit is not easy , the terminal cannot handle that much pax, but everyone is safe. the rest is only paperwork...and good training for the mechanics to change an engine by - 30 degr... No hangar that can accept a 777 in Iqaluit last time I was there...
As to the armchairs critics here : why Iqaluit? : closest airport, period. Imagine if they got into trouble after having overflown it and decided to go somewhere " more comfortable" .
