How do they dump the baggage? Does the baggage hold have bomb doors?

The activation switch was always known as the BOMB. But with the
increased terrorism threat, that term was withdrawn because of the
potential for confusion. Incidentally, I was forever having to chide
fellow crew members who would greet me with "Hi Jack". I'm not
quite sure how I would have reacted to the real thing!

So the system was renamed as Baggage Removal Activation (BRA). This of
course upset the female crew members, so they were still scratching
around for terminology when the ultimate happened. A co-pilot
accidentally operated the switch in error after landing at Stansted and
the runway was strewn with a long line baggage. We had quite a few
non-British Europeans working for, and on this occasion, the pilots
were both Spanish. In his report into the incident, the Captain wrote
of his co-pilot: "He's from Barcelona" - which just happened to
be true.

The powers-that-be decided that as the baggage dump system had never
actually been needed, the risk of unwanted dumping was unacceptable.
The CAA issued an order to all BAe146 operators to "Remove BRAs"
