Valentich Disappearance - Details

Details

Valentich had a Class Four instrument rating and 150 hours flight experience, when he filed a flight plan at Moorabbin Airport, Melbourne, on 21 October 1978. His stated intention was to fly to King Island in Bass Strait via Cape Otway, to pick up passengers, and return to Moorabbin. However, he had told his family, girlfriend and acquaintances that he intended to pick up crayfish. During the accident investigations it was learned there were no passengers waiting to be picked up at King Island, he had not ordered crayfish and could not have done so because crayfish were not available anyway.

He was flying a Cessna 182-L, with a cruising speed of around 256 km/h (160 mph), and visibility was good and winds were light. He departed Moorabbin at 18:19, contacted the Melbourne Flight Service Unit to inform them of his presence, and reported reaching Cape Otway at 19:00.

At 19:06, Valentich asked Melbourne Flight Service Officer Steve Robey for information on other aircraft below (5000 ft, 1524 m) and was told there was no known traffic at that level. Valentich said he could see a large unknown aircraft which appeared to be illuminated by four bright landing lights. He was unable to confirm its type, but said it had passed about 1,000 feet (300 m) overhead and was moving at high speed. Valentich then reported that the aircraft was approaching him from the east and said the other pilot might be purposely toying with him.

At 19:09 Robey asked Valentich to confirm his altitude and that he was unable to identify the aircraft. Valentich gave his altitude as 4500 ft and said the aircraft was "long", but it was traveling too fast for him to describe it in more detail. Valentich stopped transmitting for about 30 seconds, during which time Robey asked for an estimate of the aircraft's size. Valentich said the aircraft was "orbiting" above him and that it had a shiny metal surface and a green light on it. This was followed by 28 seconds silence before Valentich reported that the aircraft had vanished. There was a further 25-second break in communications before Valentich reported that it was now approaching from the southwest. Twenty-nine seconds later, at 19:12:09 Valentich reported that he was experiencing engine problems and was going to proceed to King Island. There was brief silence until he said "it is hovering and it's not an aircraft". This was followed by 17 seconds of unidentified noise, described as being "metallic, scraping sounds", then all contact was lost.

Famous quotes containing the word details:

    Anyone can see that to write Uncle Tom’s Cabin on the knee in the kitchen, with constant calls to cooking and other details of housework to punctuate the paragraphs, was a more difficult achievement than to write it at leisure in a quiet room.
    Anna Garlin Spencer (1851–1931)

    Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.
    Willard Van Orman Quine (b. 1908)

    Patience is a most necessary qualification for business; many a man would rather you heard his story than granted his request. One must seem to hear the unreasonable demands of the petulant, unmoved, and the tedious details of the dull, untired. That is the least price that a man must pay for a high station.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
