John Donald Buchanan was killed flying Typhoon MN494 on July 27, 1944 in the vicinity of Tilly-la-Campagne. On July 29, 1944, 609 Squadron Leader wrote, "P/O Buchanan as Raven Red Leader was given a target by 'Corker' control but owing to prevailing weather conditions was unable to go into the attack. The section did an orbit of the Caen area and then Red Leader set off to go east of the rainstorm covering the target area. At the front line flak encountered whilst the section was flying at approximately 2500 feet, Red 1 broke left followed by Red 3 (F/Sgt Adam) and Red 4 (W/O Bavington). Red 2 (F/Sgt Price) broke right and down and was last seen disappearing into the rainstorm. Red 1 called up Red 2 on two occasions but received no answer. The section then return to the Caen area and proceeded down the west side of the rainstorm which was still covering the target area. Flak was again encountered and Red 3 was hit in the tailplane, broke right and returned to base. Red 1 and Red 4 orbited the Caen area before setting off for the target area. When reaching the target area (700 yards south west of Tilly-la-Campagne) Red 1 called up and said he was going to attack. Height of cloud base at the time was 2500'. Red 1 made his attack and as Red 4 followed to make his attack, he saw him flying low over the target. Red 1 broke steeply to the right and vapour trails were seen from his wing-tips. Almost immediately, the aircraft flicked over on its back at approximately 150-200 feet crashing in flames about 400-500 yards from the target. Flak was not seen during the attack and after completing his attack on the target, Red 4 broke and returned to base. Red 4 does not think that Red 1 was hit by flak for there was no fire until the aircraft exploded on the ground."
