Different thing though. State airplane vs public transport on a commercial operator, based on (wrong) intelligence advise vs. state hijacking of a commercial third country plane. State airplanes follow different rules and sometimes have to cope with different situations. I still remember Ms Merkels plane having to wait in a hold for more than 2 hours as some country would not grant passage mid travel to Asia (and yes, an A340 with just 50 passengers and no cargo can have enough fuel for that). It happens.
However, scheduled air traffic usually does not get diverted by state hijackers or shot down by them, except in Belarus or by Russia.
