Here, at a glance, are developments today involving the crash of Pan American World Airways Flight 103 Wednesday night in Lockerbie, Scotland, that killed all 259 people aboard and more than 20 people on the ground:
A Pan Am Boeing 747 apparently exploded in the air 54 minutes after takeoff from London's Heathrow Airport. The wreckage scattered bodies and debris over 10 miles of countryside and ravaged the village of Lockerbie, Scotland. All 259 people aboard the plan and 22 on the ground were killed. Sabotage is believed to be the most likely explanation for the crash. An anonymous caller to the AP office in London claimed responsibility for the crash saying it was retaliation by the "Guardians of the Islamic Revolution" for the downing of an Iran Air Airbus by a US cruiser in July.
