Mr G.
Your experience in this tragedy is unique.
However, I hope I can correct the exact location. The site of the crash is between the flats/houses ie Moormede Est, (where I was a resident) and the A 30. The foundations of the estate were laid, and it was suggested that this area was used for the makeshift mortuary, and command area.
To use the comment of the first PC on the scene, (called by the nurse) 'they didnt tell us about this 'crash' exercise,' then it sunk in.
