Barry - still remember the announcement of leaving soviet airspace and in some cases justified.
Shortly before we rolled one day after a long taxi out we were ordered back to the ramp with our departure clearance being cancelled.
A squad of military climbed on board, went through our passengers and hauled one of them off the aircraft. Nothing was said. The dispatcher did a LMC to the load sheet, although we had burnt quite a bit of fuel we just went and worried about legal reserves later.
Always wondered what happened to the poor sod.
