On the night of March 22, I was following live ATC feeds when Air Canada Express Flight 8646 dropped off the radar at LaGuardia. A CRJ-900LR, registration C-GNJZ, operated by Jazz Aviation, had struck a Port Authority ARFF fire truck while landing on Runway 4 at 11:45 PM. Both pilots — First Officer Antoine Forest, 30, and Captain MacKenzie Gunther, 38 — were killed. Forty-one others were hospitalised.
