Surprised this hasn't been mentioned yet given the significance of the flight in question (Pa-AM Fight 103) and his connection to the former Libyan regime.

Per wikipedia:

Abdelbaset al-Megrahi, the only person convicted over the 1988 Lockerbie bombing above Scotland which killed 270 people, has died at his home in Libya.

Megrahi, 60, was convicted by a special court in the Netherlands in 2001.

He was freed from Scottish jail in 2009 on compassionate grounds because of cancer, stirring controversy when he outlived doctors' expectations.

UK Prime Minister David Cameron said it was a day to remember the 270 victims of "an appalling terrorist act".

Mr Cameron, who is in Chicago for a Nato summit, said Megrahi should never have been freed, Reuters news agency reports.

Scottish First Minister Alex Salmond also said Megrahi's death was an occasion to remember the victims of Lockerbie.

He said Lockerbie was still a live investigation and that Scottish prosecutors had never believed Megrahi was the only person responsible.

Relatives' anger
Megrahi's release sparked the fury of many of the relatives of the victims of the Lockerbie disaster. The US - whose citizens accounted for 189 of the dead - also criticised the move.

But others believed he was not guilty of the bombing.

Dr Jim Swire, whose daughter Flora died at Lockerbie, called Megrahi's death a "very sad event".

"Right up to the end he was determined, for his family's sake... [that] the verdict against him should be overturned," said Dr Swire, who is a member of the Justice for Megrahi group.
