Many people remember exactly where they were when they heard that a plane had crashed, just days before Christmas.
There are also those who actually witnessed the horror at Lockerbie first hand.
Some are only now, 25 years later, able to talk about their experiences.
The family of Abdelbaset al-Megrahi, the only person to be convicted of the Lockerbie bombing, say they plan to appeal against his conviction. Libyan Megrahi was convicted of the bombing of Pan Am flight 103 in which 270 people died 25 years ago.
Magrahi lodged a second appeal against his conviction from behind bars in Scotland where he was serving life for mass murder. However he dropped his case two days before he was released on compassionate grounds by the Scottish Government. He was suffering with prostate cancer.
Magrahi died last year protesting his innocence. Tonight, his brother said that his family plans to appeal the conviction. It comes as members of the UK Families Flight 103 group announced they are also considering their own appeal against Megrahi's conviction in a bid to reach the truth.
A special link has developed between Lockerbie Academy and Syracuse University in the United States, which lost 35 of its students in the Lockerbie bombing.

In the aftermath of the bombing of Pan Am flight 103, ordinary people in and around the scene played a big part in the recovery operation. Eric Milligan was a gardener working for Dumfries and Galloway Councillor.
As he drove a van, he was sent to Lockerbie to assist with collecting bodies. He's told his story for the first time to ITV Border Correspondent Hannah McNulty:
Scotland's first minister Alex Salmond has announced that the Scottish Government will give £60,000 to the Lockerbie Scholarship fund.
The fund pays for students from Lockerbie Academy to spend a year at Syracuse University in America.
The connection between the two institutions was forged less than two years after the Lockerbie bombing which happened 25-years-ago on Saturday.
35 students from Syracuse were killed on board flight Pan Am 103 when it was blown up in the skies above Lockerbie.
