My wife was a flight supervisor/purser with Midland at the time and shared a house with the flight supervisor on the BD92. About six months later, Midland had an identical issue with a B737-400 on the same route. On this occasion, my wife was the senior cabin crew member on board and she went into the FD and pointed at the side she had seen flames/sparks coming from, rather than say L or R, 1 or 2. The aircraft subsequently diverted to EMA and the CC were then required to operate on a DC9 to take the pax across to BFS!
