On 30 November 1961 a Vickers Viscount aircraft departed from Sydney in the evening for a flight of to Canberra. There were thunderstorms to the north and south of the airport. From about 9 minutes after takeoff the crew of Ansett-ANA Flight 325 did not respond to radio calls. The flight did not arrive at its destination and authorities received no report of a crash. Throughout the night no-one knew the fate of the aircraft or its occupants. The next day wreckage and a fuel slick were found on the surface of Botany Bay. The aircraft had been drawn into a thunderstorm and subjected to extreme turbulence. It had broken up and crashed into Botany Bay, less than 3 statute miles from where it took off. All fifteen people on board died.〔(The Loss of Viscount VH-TVC in Botany Bay ) Retrieved 9 September 2011〕〔(Vickers Viscount Network ) Retrieved 9 September 2011〕〔(Aviation Safety Network ) Retrieved 9 September 2011〕 The loss of Ansett-ANA Flight 325 was the first fatal accident suffered by Ansett since commencement of operations as Ansett Airways Pty Ltd in 1935. ==The flight== Ansett-ANA Flight 325, a Vickers Viscount registered VH-TVC, took off from Sydney airport on runway 07 at 7:17 pm local time for a scheduled passenger flight to Canberra. On board were the pilot, Stan Lindsay; co-pilot, Ben Costello; two air hostesses, Aileen Keldie〔Robinson, Margaret (1996).

Above Sydney airport there was cloud at about but no thunderstorm activity. Flight 325 was observed to enter cloud shortly after take off. Five other aircraft took off while this meteorological situation existed.〔 Flight 325 was directed to take-off and continue heading east towards the Tasman Sea until reaching an altitude of , turn around and fly west to a radio navigation aid west of the airport and then turn south-west for Canberra. The crew were to ensure they passed over the airport no lower than .〔 Five minutes after takeoff the crew advised they had reached . About 3½ minutes later, Sydney air traffic control called Flight 325 with a routine request for information but received no reply. No further radio communication was received from Flight 325 so when it did not arrive at Canberra airport authorities knew it had suffered an accident. An air search was planned to commence at dawn.〔〔("Airliner Believed Down In Sea" ) ''The Canberra Times'' – 1 December 1961, p.1 (National Library of Australia) Retrieved 26 December 2013〕 Approximately 9 minutes after takeoff the outer section of the right wing had been torn away and the aircraft had crashed into Botany Bay.〔 The rain, thunder and lightning associated with the thunderstorm over Botany Bay had been so intense that no-one saw the aircraft or observed anything crash into the water. Accident Investigator Frank Yeend wrote "The weather was so bad that this aircraft crashed in the middle of a major city without anybody having seen it or heard anything that would give cause to alarm."〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ansett-ANA Flight 325」の詳細全文を読む スポンサード リンク
