It is not a new 139 and it is not owned by Ornge. It is a leased, used 139, that they got at a very favourable rate.
The 139 should be a great leap forward for the Moosonee base and should provide cost savings for Ornge now that they can finally consolidate spares for one type as opposed to supporting two helicopter types.
They probably should have looked at NVG compatibility during the purchase process, but evidently they did not and are now retrofitting. STARS have been operating on NVG's quite happily and safely for years and reap the benefits. Ornge should too!
