So sorry to hear sounds like a nightmare. I had a very similar experience. Don't remember the airline, it was in the early 90's. We boarded on time and were on the runway engines all fired up started for take off and the pilot came to a sudden stop HOLY $h!t. So we went back to gate told we had mechanical problems and sat on the plane for about an hour. They told us we had to deboard and than went in the terminal for hours and finally told we had to stay overnight in Mobay. It was a full plane and they put us up at Sandals (not a fan of) We were given 5 rooms to share between all of us and no luggage, they did give us food vouchers. NIGHTMARE to say the least but I guess it could of been worse had we of taken off
