Oh yes. Used to position on them all the time. When the cabin wasn't filling with smoke, the avionics were frying themselves... it was better when it was a 748! I also seem to recall lots of trim problems - making all the pax sit down the back, and loading ballast spring to mind.
When we first introduced them, they were tech all the time - hence the nickname Advanced Technical Problem. Eventually, BAe sent a team of engineers from Prestwick to monitor them on a 24 hour basis, as they were failing to dispatch 40% of the time.
Of course the real proof of the pudding is in how many they sold, which was very few. There were still a bunch of them parked at Woodford last time I was there.
It could have been a good aircraft, but they rushed the development process and cut corners, and it shows.
