757 & 767 overwing doors. External entry?
 

During a Tech refresher course, some bright young thing asked if the fire service (or maybe engineers if in the hangar?) had any means of opening the non-service doors from the outside. Y'know, passenger doesn't pay attention to the safety briefing and can't open a door, fireman stands on the wing etc etc. I've not noticed anything on a walkround but wondered if anyone knew if there was any external access to the deployment mechanism.

First time I've been asked this in 12 years of flying them.:confused:

Yes they can be opened from the outside. Depending on the configuration the overwing escape slide is disarmed when opened from outside.
