An open door in and of itself is not what i consider to be an "Emergency" situation. The fact the window in the door disappeared....does not in itself add urgency to the situation.
If there had been any other indication of a problem....sudden onset of vibrations, control feedback, unusual sounds from the rotor system, change in Main rotor track or appearance.....yes then....there would have been some urgency to the landing.
The crew did absolutely fine in landing the aircraft and shutting down to do a proper visual inspection of the airframe, rotor blades, and tail rotor. Upon finding no damage and absent any unusual indications....I would have cranked back up and returned to the maintenance base.
Let's not get crossed up over semantics or terminology.
What I am trying to understand is why the Feds got called and the delay in removing the aircraft when there had not been any damage to the aircraft beyond the missing window panel.
Sounds to me like some folks are getting gun shy at Ornge with all of the investigations going on currently.
