CALGARY — WestJet says early results of an investigation into an ice chunk that crashed through a Calgary home indicate one of its planes is to blame. Airline spokeswoman Lauren Stewart said in an email that a preliminary investigation has concluded the ice on Friday evening fell from a WestJet plane on approach into Calgary from Regina. Stewart said WestJet is inspecting the aircraft to determine the cause of the incident and is co-operating with local authorities and Nav Canada, the agency that is responsible for Canada’s civilian air navigation service.
