Lets assume 2 things

1. the door is about 6ft tall by 3 ft wide (this yields 2,592 sq inches of door surface)

2. further assume the cabin pressure differential at cruise altitude is about 6 psi (realistic)

this means that 6 lbs of pressure is holding every single square inch of this door in place.

the man would have to be able to PULL using his arms, with over 15,000 lbs of force. He would literally have to be strong enough to pull 3 of these without assistance using only his hands.


Uhhh... not happening

even if he managed to get it open all the way by sheer GOD LIKE arm strength equivalent to a dozen men or more... the rate of decompression through such an orifice would be virtually instantaneous (not this drawn out 5 minutes of suction B.S. you see in the movies), if you were sitting in the seat a few rows back buckled in the suction force would probably barely ruffle your hair.

the only casualty would be the man holding the door handle - and who gives a damn about him?

and on the subject of explosive bolts... civilian airliners may have explosive bolts - but these are usually only found on landing gear doors or in rare cases they can be found on blow out panels in a rear bulkhead not accessible from within the cabin... explosive bolts are generally NOT on cabin doors though they CAN be.
aaah never argue with a pilot

Lesson learned next time smash the window and get out from it instead
