Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.Pan Am Flight 103 conspiracy theories suggest a number of alternative explanations for the bombing of Pan Am Flight 103 on 21 December 1988. Some of the theories preceded the official investigation by Scottish police and the FBI; others arose through a different interpretation of evidence presented at Libyan agent Abdelbaset Ali Mohmed Al Megrahi''s 2000/2001 trial; yet others have been developed independently by individuals and organisations outside the official investigation.
