This certificate was presented to Wal Walters to commemorate the destruction of two turbo starters on GAF Canberra Mk 20 A84-225. The incident also damaged both engines, one of which had to be changed. Wal had been unfortunate enough to encounter two faulty turbo starters on the same aeroplane at the same time. The incident is believed to have occurred on 14 November 1963. Image: Wal Walters Collection
