today I tried to do a flight from London Heathrow to Chicago O’Hare International in British Airways’s b747-400 and upon arrival in KORD, my b747-400 tail spun on the runway and skidded off the runway onto the taxiway where it then crashed. I would not have minded this problem I’m having if this were the first time it is happening, but this has also happened to me in the past. That last time, I did a flight from London Heathrow to Delhi International, again a British Airways b747-400, and the same thing happened. Upon both arrivals, I had full flaps, and spoilers armed. Can someone help me? I’m starting to fear flying the b747-400 anymore and I don’t want that to happen!
