|04FEB59||On this day Neptune A89-308 from No 11 Squadron became the only aircraft of this type lost in 26 years of service with the RAAF. While on a local training exercise in the vicinity of the unitís Richmond base, the crew discovered a severe fire in the starboard engine nacelle. Realising the gravity of the situation, Squadron Leader Geoff Cullen, a very experienced Neptune captain, initially reported that he was returning immediately to land. A minute later he advised that he would have to make a crashlanding to the north of the airfield. Within seconds, as the aircraft passed less than 100 feet above the Hawkesbury River, the starboard mainplane folded, and A89-308 crashed upside down into the river bank less than three kilometres from the RAAF base. The aircraft exploded on impact and, tragically, all eight men on board were killed. (Source: Office of Air Force History)|
