25F
If this was all pre-planned, why would Belarus leave it until the flight was almost out of their airspace before acting?
They didn't though did they?
If the transcript is to be believed...
:
The flight first made contact with Belarus ATC at the boundary inbound at 0929 UTC.
ATC first mentioned the bomb just
two minutes later at about 0931 UTC....
The flight continued northwards with the discussion/request for clarification continuing, culminating in ATC calling it a red threat at 0945 UTC
It sounds more to me as if it was trap set just waiting to be tripped pretty much the moment they entered the FIR....
