Back-to-back deadly crashes ‘ just coincidence’: Bombardier

Rescuers work after a Bombardier Q400 passenger plane arriving from Bangladesh crashed at the airport in Kathmandu, Nepal, on Monday killing at least 49 of the 71 passengers on board. The crash followed another deadly incident, on Suday, involving a Bombardier Challenger business jet. Eleven were killed when the private aircraft struck an Iranian mountainside.
