an extreme case where suddenness may have happened

A good friend from Australia explained to me why she always flies business class on domestic flights in India. Her case is indisputable.

Some years ago she was flying between to two cities in India on one of the many domestic carriers. The plane trundled off to the runway but stopped short on one of the taxiways. After ten minutes or so, some steps and a small airport bus appeared. All the business class passengers including my friend were off-loaded and taken back to the terminal, leaving the economy passengers on the plane.

Back in the lounge, my friend asked what was happening, why had the business class passengers been bussed back to the terminal leaving the others behind on the plane. "Madam, there is a bomb scare on that plane..."

See, you can't argue about that!
