Mild curiosity.
The mildly intriguing thing is Tiger, Virgin and now Qantas have had ground paper work systems at the root of later 'trouble', is this becoming a 'trend?. Couple or three stuff ups a year would be about par for the course. If more than three have slipped through to the keeper, how many have slid by un-remarked. Understaffed?, under-trained?, computer glitches or plain old fashioned 'stuff-ups' and finger trouble: perhaps a combination.
Not a research project – passing interest only – wouldn't bother except the threads were shut down. Passing strange. Comments – anyone??
