about the pictures that eye witnesses have been showing, its a B727...T tail with a third engine on the tail.
about the large area of debris, wouldnt a relatively flat high forward speed crash cause a rather long debris trail?
if the info on the altitude is correct, sounds like a microburst to me.
as for crew being threatened. there is a lack of type rated pilots in pakistan. alot of unemployed pilot yes, but most of them are SE and military time, not heavy metal. bhoja barely has enough crew to field for the fleet, so does shaheen. Airblue on the other hand has crew saturation.
the weather was bad, it wasn't THAT bad to call for a diversion, but this is just a personal observation from the ground. yes there was an active cell near the field, but i have seen BA, EY EK QR and others come into OPRN with with worse conditions.
Btw, Bhoja is a the family name for the owners.
