The aircraft had taken off just half an hour earlier from London Heathrow and was on its way to New York with 243 passengers and 16 crew on board, when a Semtex bomb hidden in a suitcase detonated at 31,000 feet.
By 7.03pm, a deadly combination of mangled fuselage and burning aviation fuel had rained down upon the town of Lockerbie with lethal force, with the ensuing fireball incinerating homes in the town's Sherwood Crescent and, with it, 11 residents.
Meanwhile, the bodies of the tragic passengers on board the doomed flight and their personal belongings were scattered on residential streets, surrounding gardens and the countryside around.
Victim: Student Lindsey Otenasek, from Syracuse University in New York, wanted to teach children
But for Mr Giesecke, now 65, the discovery that night of one of those lost souls – Lindsey Otenasek, the 21-year-old Syracuse University student who landed on his hedge in the back garden – forged an unbreakable bond of friendship with her family in the United States.
To this day, Lindsey's mother, Peggy, 85, still cherishes two small pebbles from Mr Giesecke's garden she took as a permanent reminder of the spot where her daughter – the youngest of her six children - was found, and of the Scottish town which treated her and other victims with such kindness and respect.
Last night, Mr Giesecke recalled the moment the families met for the first time, saying: 'About a year after the bombing, I remember working in my garden when I saw a couple standing uncertainly on the pavement outside my gate.
The woman looked at me and said 'I believe my daughter Lindsey was found in your garden.'
'We'd been used to families visiting in the streets around in similar circumstances and so their visit wasn't really unexpected. I'd never learned the identity of the girl on my hedge but I'd never forgotten her.'
He added: 'The garden and the area had all been cleaned up by then. The hedge was gone and there were fresh pebbles down. I showed her exactly where I'd found her and she was very grateful I could explain what happened that night.
