For bad reason: 1970. Air Rhodesia Viscount Salisbury (as was) to JNB. Left about 9am had breakfast just in time for going through a thunderstorm. The Viscount ceiling was (I think) about Fl160. so could not go over it and possibly too wide to go around. I'm also guessing that the flight crew were well used to it and customer comfort may not have been a priority. I kept my breakfast but many did not.
For good reason: 6th August 2003. Concorde G-BOAC LHR to JFK. No more needs to be said.
