It's actually standard procedure for airborne security threats. If intelligence comes through that the aircraft is intended to explode over a large conurbation for example, it can be taken down in a remote, unpopulated area or out over the sea. What if the package in the hold was able to be activated by a passenger? Or someone one the ground with an ADS-B receiver?
I know.
You don't need to shoot it down, instruct the pilot to go elsewhere. If he doesn't or clear evidence of an imminent threat does emerge, then by all means go airborne.
I can't see such detailed information coming through, not in this case. They had a 'potentially sinister' consignment, and the planes were following it to its original destination as I understand it.
It seems very superflous to me.
After the confusion and conflicting statements, I don't think its anything like a bomb. The intelligence passed along must have been to that effect, it couldn't be anything else given the haphazard dealing with it today (tested three times, police packing up then coming back etc).
It's a show. A pretence.
