The experience reported (names of dogs aside) was that something substantial flew by her (dirt it seems) simultaneously with a boom or cracking sound, and then a plopping sound and the appearance of a smoking hole in the ground. Except for the fizzing and crackling that came from within the hole following the incident, it would be fairly convincing. I'm sure that with the disorientation that would accompany such an experience, most on the list would draw a similar initial conclusion, (ie: that something had impacted the ground rather than that something had errupted from it). Knowledge would have shown those on the list that the sounds issuing form the hole were inconsistent with a meteorite impact, but the smoke bit (steam probably - a few wisps anyway - could be easily interpreted (in the 'heat' of the moment) with this perception. (Fire a gun into mud and you might see a little bit of steam or vapor, whether from heat of impact, or violent displacement.) Similar (slight) results might be seen from condensation vapor as a 200 below 0 F. object interacted with the air (like when you open your freezer door. Similarly, there is only a very tiny range of temperatures (50 below zero to 250 or so F) that an object might be when coming into contact with wet earth and not be expected to make some small sounds resulting from the sudden expansion of water as it freezes or evaporates or from the sudden expansion of the object as a broken 200 sub zero interior is inundated with 50 degree water from the mud. Calm minds sitting at computers think differently than those who have just had something blow up next to them. I'm afraid I might have reached my hand into the hole to settle the hot/cold question and gotten a mighty jolt. -Robert Beauford : ) From: Ron Baalke <baalke_at_zagami.jpl.nasa.gov> http://www.telegraph.co.uk/et?ac=002549632124328&rtmo=weAiMMib&atmo=rrrrrrrq &pg=/et/01/3/2/nufo02.html UFO Fever Comes Down To Earth With A Bang By Robert Uhlig Daily Telegraph March 2, 2001 WITH a supersonic boom, a whoosh and a plop, meteorite hysteria fell to Earth in a sleepy suburb yesterday morning, leaving a smouldering, fizzing hole a few feet from a startled woman walking her dogs. Sylvia Mercer had her close encounter with an unidentified heavenly object in a quiet country lane in Hopgrove, York. "I was walking my dogs when I heard two bangs," she said. "Then there was a rush of wind whistling past my head and a plopping noise. I froze in terror and thought my last moments had come. When I looked at the ground I saw a smouldering hole. "There was smoke and noise coming from it and it was making strange and frightening sounds. You don't usually expect to get attacked from outer space while you are out for a stroll. It is absolutely amazing." She ran home to raise the alarm and then returned to cover the 12in-wide and 5ft-deep hole with a dustbin lid. Within minutes, police, the Army Bomb Disposal Squad from Catterick, university geologists and museum experts from York were rushing to the scene. As police sealed off the crater and prepared to evacuate the area, meteorite experts at the Natural History Museum in London were commandeering cars, ready to race to York to examine what they were promised was a brain-sized 12lb lump of primordial space rock. Phil Manning, keeper of geology at the Yorkshire Museum, was one of the first specialists on the scene. He said it was the biggest meteorite to hit Britain for 100 years. "The bangs Sylvia heard were sonic booms. The meteorite would be travelling at the speed of sound and the hissing and popping were caused by the heat it discharged," he said. A policewoman who was ordering locals to keep away told reporters that the hole had certainly been caused by a meteor impact. "We just cannot attribute it to anything else." While bomb disposal experts peered into the hole, scientists developed theories to explain its strange blue colouration. Only the meteor and planetary experts at the Natural History Museum in London urged caution at the growing meteorite hysteria. A mechanical digger brought in to excavate and retrieve the rock found nothing. And nine hours after Mrs Mercer's narrow escape, experts told her that it was nothing more than a low-flying clod of earth. A high-powered electricity cable, buried 3ft deep, had split, shorted and blown - causing the gurgling and popping noises. A spokesman for City of York council said: "The hole was caused by the earth being blown out, not by an object going in at high speed and burying itself. What flew past Mrs Mercer's head was nothing more than a big clod of earth." Last night Mrs Mercer said: "I'm quite disappointed to discover I've not survived a meteorite falling from the skies at the speed of sound. But it will give someone a laugh to discover we were all fooled." Received on Fri 02 Mar 2001 02:44:12 PM PST |
