It's a shame that professional pilots are not as clairvoyant as Cokney Steve or Tourist, who seem to know by divine inspiration when to ignore emergency instructions. In addition to the custodial sentence, perhaps a lifetime ban on flying with any airline would also be appropriate. For those two, and others making similar arguments, it's a shame they can't be identified by the ISPs and banned now before they do kill another passenger.
When things go wrong, every split second makes the difference. I suggest the pair of you have a look for footage of the Chinese 737 that went up at Okinawa. That was only half full. Imagine twice the number of passengers, but half the exit rate because of people clogging up the aisle and exits with hld alls and backpacks.
An evacuation may or may not have been warranted in this case. I'm not going t second guess the crew - none of us should do that because we don't know what information they had at the time. But evacuations are not initiated lightly, and each should be treated as the utmost emergency. Ill-informed second guessing and selfish disobedience by greedy passengers is a massive threat to life. Perhaps, since it seems to be so deliberate rather than panic induced, as demonstrated by our respondents above, it should be treated as attempted murder?
