1. Was the Lockerbie bomber a US spy?
In 2008, Scotland's top legal expert, professor Robert Black, urged the UK government to answer reports that there is evidence that Abu Nidal was a US agent.
Black believes Abu Nidal was responsible for co-ordinating the bomb that blew up Pan Am flight 103 over Lockerbie
In 1993, Margaret Thatcher, in her memoirs, wrote that after she backed the US bombing of Tripoli in 1986, “There was a marked decline in Libyan-sponsored terrorism in succeeding years.”

2. Apparently, both the US ambassador to Lebanon, John McCarthy, and the South African Foreign Minister Pik Botha had their travel plans altered at the last minute in order to avoid PanAm 103.
Others, including Charles McKee, a US Army Special Forces Major, and Matthew Gannon, the CIA's Beirut deputy station chief, uniquely amongst US officials, changed their plans at the last minute to fly on PanAm 103. - LOCKERBIE BALONEY UNRAVELS - Mombu the Culture Forum
3. Minutes before PanAm flight 103 took off from London's Heathrow airport, FBI Assistant Director Oliver 'Buck' Revell took his son and daughter-in-law off the plane. 
Revell was an associate of Lt. Colonel Oliver North who was linked to Iran-Contra. .

Monzer al Kassar, allegedly worked for Oliver North and allegedly was part of Operation Corea.
4. The Herald newspaper was told that the CIA offered $2m (£1m) to the key witness in the Lockerbie trial and his brother.
"Recently discovered papers" show that Scottish police officers were aware the US intelligence service had discussed financial terms with Tony Gauci and his brother, Paul.

5. On 17 April 1999, Russell Warren Howe, in the Guardian, explained how Israeli intelligence was among those that had a motive for blowing up Pan Am 103 over Lockerbie. (What if they are innocent? UK news guardian.co.uk)
According to Howe:
In 1986 a bomb exploded at Berlin's La belle disco club. Libya was blamed, on false evidence, and Reagan bombed Tripoli.
German TV exposed how the CIA and Mossad had links to the 1986 Berlin disco bombing.
Victor Ostrovsky is a Canadian who worked for Mossad.
According to Ostrovsky, Mossad tried to frame Libya by transmitting a fake message.
Ostrovsky testified that it was Mossad who set up a transmitter in Tripoli that generated a false signal about the "success" of the Berlin bomb.
There was a similar 'fake' message about Lockerbie, which may be the work of Mossad.
In one of his books, the author Gordon Thomas argues that the tagging and smuggling aboard of the lethal Lockerbie suitcase was organised by Mossad.
Gordon Thomas recounts how a Mossad officer from the London station turned up in Lockerbie just after the crash, and arranged for the removal of a suitcase belonging to a US intelligence officer in the US Defence Intelligence Agency , Charles McKee.
McKee's case was found after the crash by Jim Wilson of Tundergarth Mains farm, and contained what looked to Wilson like cocaine or heroin samples.
Within hours the Lockerbie bombing, two planeloads of 'US intelligence people' arrived at the site, and a Scottish radio reporter, David Johnston, soon heard that the bomb's target had been a group of US intelligence officials travelling back from Beirut.
McKee's suitcase "presumably contained his files on the CIA-Hizbullah-Mossad drugs ring" which McKee had discovered.
"Defence sources in Washington agree ... that McKee's group had been frustrated by the cover-up of the CIA drugs scheme (OPERATION COREA), and was returning home to insist that it be exposed."
What about Iran?
It is unlikely that Iran would use "a secular, even Marxist, Arab nationalist" member of a Palestinian cell to attack the USA.
It is entirely possible that Megrahi ... is being framed.
6. In 2007, Phillip Marlowe wrote an article entitled: The COREA Connection? Part I …
From this we learn:
Amiran Nir worked as Israel’s terrorism consultant to PM Shimon Peres.
Nir worked with the US on the Iran-Contra, Arms for Hostages deal; jointly run by the US and Israel.
Nir teaming up with Col. Oliver North in these efforts.
Nir is thought to have had incriminating evidence on Bush.
Nir was lured to Mexico to die in a mysterious plane accident.
A US Navy commander has claimed that George H. W. Bush, Sr. and Amiran Nir met at Jerusalem’s King David Hotel on July 29, 1986 to brief him on the Arms for Hostages deal.
According to Joel Bainerman: “Nir was secretly taping the entire conversation. And this provided evidence linking Bush to the Arms for Hostages deal. At the meeting were McKee and Gannon, who would die in the Pan Am flight 103 over Lockerbie.”
Nir may have had evidence of Bush’s involvement in Iran-Contra and even in the COREA drug smuggling group?
7. In 1988, the FBI's Robert Mueller supervised the Lockerbie Bombing investigation.
"He successfully kept the CIA's connection to the bombing from becoming public.
"The CIA and FBI took control of the crash scene for the first day (keeping Scottish police at bay), searching through and removing numerous pieces of evidence and luggage from the wreckage to obscure the connections of the bombing to the CIA special team that was on board the aircraft.
"One CIA defector has said that the team had been returning to the states against orders to blow the whistle on CIA drug and terrorist connections in the Middle East." - FEDERAL BUREAU OF INVESTIGATION ·
