A passenger aboard an Air Canada flight from Toronto to Dubai opened a cabin door and fell to the tarmac before takeoff Monday evening, injuring themselves and causing lengthy delays.
The plane, a Boeing 777, was sitting on the tarmac at Toronto Pearson International Airport preparing for takeoff when the incident took place.
Air Canada confirmed to Global News that during the boarding of flight AC056, a passenger “who had boarded the aircraft normally,” opened a cabin door on the opposite side of the aircraft, instead of going to their seat while the aircraft was at the gate.
As a result, the passenger sustained injuries falling to the tarmac, and emergency services and authorities were called in.



Important to note that airplane doors literally cannot be opened while the plane is pressurized, as it is during flight. There are several tons of air pressure holding them shut. This sort of mishap is only possible on the ground.
Should probably have some kind of anti-idiot lock on it anyway, but maybe it did and this was just a particularly clever idiot.
Anti idiot locks would be an emergency situation nightmare.
Everything worked as intended. The only person injured was the idiot, and no one else was at risk. They could have just as easily opened a door on the gate path thingy (no idea what the name is. Connecting the terminal gate to the plane) and yeeted themselves out that way, for the same effect.
Jetway is the word you’re looking for
I think it’s a jet bridge.
It’s ok, I’m a limo driver!
Unless it’s a Boeing 737 Max 9
‘on the ground’ AKA a door 4.5 metres above the ground
‘the ground’ AKA solid bitumen
( Might be time to cross-check and arm unused-doors before any passengers board )
I still can’t believe this occurred.
I thought it was external airflow due to air speed, but it seems like you’re right, it’s due to cabin pressure.
