Back in the QLink 146 days, not all that long after Sept 11, a flight left BNE (that's IATA for YBBN which is ICAO) for either ROK (IATA for the ICAO YBRK) or MKY (IATA for the ICAO YBMK), with a gentleman on board who just happened to be from the good ole U.S of A, and who happened to be in New York City on Sept 11.
He was agitated that his breakfast had been served with white powder on top of the bread roll - "ANTHRAX!"
The aircraft sat on the Tarmac at destination, doors closed & pax and crew on board, for some hours whilst the authorities tried to work out how to deal with this dastardly attack. At one point the authorities worked out that the APU aircon was possibly pumping anthrax laden air into the atmosphere, and asked the crew to shut it down. Given the tropical conditions, thankfully sanity prevailed!
