End of the 225
Long term: No idea, but the history of aircraft being removed from commercial service due to lack of passenger confidence goes right back to the Comet (Concorde, Chinook et al)
Short term: CHC plus Zenon are both looking for S92 pilots for Aberdeen, the Zenon recruitment says 12 month contracts. To me that indicates that no one expects to see the 225 released back to the line in the UK any time soon.
