This does not specifically answer your query, but I guess you noticed RV Palesy (Aus.413027) has a casualty file in relation to FL827? According to the diary of LD O’Connor (Aus.430394) - Palesy was with 258 Sqn RAF when the unit were converting from Hurricanes to Thunderbolts. This fits with the casualty file date of 29 Sept 44. Ralph apparently broke his leg when bailing out at 500ft during a training flight (a google search shows this was a collision with HD141). It seems Palesy may have rejoined 258 around May 45.
