An attack by a German night fighter caused a fire at the rear of the starboard engine on Ward's plane.
At an altitude of 13,000 feet, flying at a speed of 145km/h and in total darkness, Ward climbed out through a hatch, crawled out on to the wing and beat out a fire in the fuel system, using the aircraft's canvas cockpit cover.
He kicked or tore holes in the aircraft's fabric with a fire axe to give himself hand and foot holes to reach the engine.
Instead of the crew having to bail out, the aircraft made an emergency landing at Newmarket, United Kingdom.
Ward was killed in action three months later when his plane was hit by flak over Hamburg. The Victoria Cross was presented to his parents by the Governor-General of New Zealand at Government House, Wellington in October 1942.
The assembly hall at City College is named after him.
