If said entity wants a “delivery system” they have to have something to deliver. I’m assuming you mean a nuke. I would think any organization that had the resources to get a nuke could get a plane way easier than going through all this trouble.
You make great points.
Lessay it’s suicide by pilot or co-pilot over a woman or something:
If he’s sad/angry enough to kill 240 people, wouldn’t he be mad enough to fly the airplane into KL’s muzzie twin towers..?
In that state of mind why simply settle for smacking into plain ole’ water?
I have to allow that the, “de-pressurize cabin, then suicide by pilot or co-pilot” does seem simple and convincing.
