First of all, I guarantee you that the 747 is designed with a warning if the gear is not down with landing flap down. Even the old 727 had it.complexintentions wrote:I love stories from past eras, but they're just that - interesting stories from past eras. Things to learn from. And so we have: present-generation equipment will not allow the aircraft to be configured the way it was in the B747 story without a configuration warning blaring the entire time. If you could somehow sleep through that, there's also the GPWS warning "TOO LOW, GEAR". I doubt that very many landings are ever in need of these warnings, but they are there. Thus when was the last time (or even in this delightful little anecdote) an airliner accidentally landed gear-up, please?
As for landing with the gear up in an airliner...PIA did do it in a 747, Continental in a DC-9 and Continental once again scraped the runway on a go-around due to them being told that the gear was not down. All this just from memory. I am sure there are more.
If you take the time to read the story carefully, you will see that it could easily be applicable to this era in some cases, although I believe Boeing has added an 800' RA constraint as well to the warning of the gear not being down....to cover more possibilities.
