Thanks! That's exactly what I meant (especially the Tri Star one)
I do remember the inertia reels, and the roof hatches, I am sure a pilot once pointed one out on an A320...?
As for the guy peeking out of the top of that last pic, maybe it was just hot in there???

I had wondered about the possibility of an escape thru the avionics bay, especially with the 330. Once on a turnaround, a 330 was in the bay, and an engineer appeared to open a panel in the nose, just forward of the nose gear compartment, did something, then closed it again. It made me think whether you could get into the inside of the plane from the ground - and so it appears to be possible!
