Thank you for info. re Accident Cards. I was on the spot at the time, but this M-A-C has always troubled me, so more recently I gathered all the information together, including a copy of the Court of Inquiry, available from RCAF authorities. Unfortunately, vital appendices giving extracts from the Flying Control and R/T logs were withheld. I produced a comprehensive report, and copies now reside with DORIS at the RAF Museum, London, AHB RAF Northolt, and with the archives at Tiree. Can provide you with a copy if you wish.
