Master Rocket Polisher,
AD crews are good, I'll admit, however clairvoyance is not an entry requirement, nor is it in the training syllabus. Tell me exactly how an attendant F3 crew are meant to know:
1. Exactly who is in control of the aircraft.
2. What their intentions are.
3. Whether or not a hijacker / potential 'shoe bomber' has been subdued / tied up / hooded / given the kicking they deserved by the cabin crew / pax.
If the attendant interceptor cannot determine the above, a controller on the ground looking at a radar return has even less of a chance.
Seems like you have an unfulfilled dream in there somewhere - either that or you're just an ignorant tw@t.
