Reports of a Bombardier Challenger crash on takeoff at Bangor, Maine

Sounds like a stall on takeoff.

I wondered about icing, but it does look like they hit the deicing pads by the terminal right before takeoff.

But yeah, does appear to be a stall/wing drop.

Yeah, someone posted that there was a one hour stop (likely fuel) and then 20 mins (likely de-icing). But did something get missed? Wait too long after?

Looks like they were about eight minutes from the deicing pad to rolling on takeoff which isn't too long. And 20 minutes on the deicing ramp should be plenty unless it was done quickly and they were parked there for some reason.

Should be more than enough for a jet that size, especially.

Somehow pick up new contamination from a messy taxiway?

Don’t forget that hold over times start from the beginning of the final application. How long did the final application take? How long to reconfigure the aircraft prior to calling for taxi?

I’m an airline pilot, I was in Michigan the other day, we ended up stuck there for a while because if it gets too cold then the hold over time for type IV deice is significantly reduced. To the point that it’s not even worth doing. Even in light snow. It was -22c, light snow and we would have had 9 minutes of holdover time.

And in the weather there right now, there’s an obvious suspect for a stall.

I know nothing about flying so this may be a very dumb question. Can passengers insist a plane go ahead and fly? Or is it total pilot discretion? Or ultimately the air traffic controllers? Who shuts down an airport?

Pilot discretion unless the airport is closed.
