usually I like your posts, showing knowledge and understanding of the technical aspects of aerial naviagation.
HOWEVER, I disagree here with you
The captain can be wrong and if he has ANYTHING brought to his attention he should work to make everyone reasonably content about the safe continuation of the operation.
This was not done here. poster TWO's IN has the concept quite right. Who has access to the apu area of the plane? Mechanics who probably wouldn't want anyone hurt...OR some bad guy who did want someone hurt. Recently in San Jose , California, USA someone managed to get into the wheel well on a 767 to Hawaii. Breaches in airport security are becoming MORE commonplace and grabbing ascafolding/ladder and compromising the plane is a possibility.
Someone is wrong here, but it is not the FAs. Running an airline is always secondary to safety at an airline...isn't it?
