What are you talking about BOAC?
There was a threat to set fire to the aircraft, where, when or how has not yet been determined, no question of over dramatization, I made the point that they diverted before heading out over the Atlantic where their options would be severely limited and WHBM scoffed at this, so I gave an example where 229 people died and illustrates the need to get down, configured and landed in very short order, somewhere close at hand. The simulator exercise, with smoke in the SIM, brings this home all too quickly, you should try it.
