I'm really surprised the passengers put up with it for that length of time. I was once on a plane that got diverted to Pittsburgh because of thunderstorms in Philadelphia. We sat on the tarmac for a couple of hours and they wouldn't let us out. We then started taxiing and got stopped again. Finally they informed us that there wasn't enough fuel in the plane to get to Philadelphia and we had to go back to the gate. Passengers were getting very irate so they opened the door and let us out and told us we had to be back in X minutes.
I was completely fed up. Since Philadelphia was just a stop before my final destination in Rochester, my wife and I simply went to the counter and asked for a direct flight from Pittsburgh to Rochester.
