'Mr. Lindenbaum had two bags, a smal one and a larger canvas duffel. Agent Sartore informed Mr. Lindenbaum that there was no overhead space left for the duffel and that it was too large to fit under the seat. He tagged the bag and told Lindenbaum to leave it on the jetway and the baggage handler would take care of it. Mr. Lindenbaum then removed a knitted fabric sport jacket, put it in the duffel, and boarded the aircraft.'

Jackson brought up a credit card receipt.

'Mr. Lindenbaum's credit card records reflect the purchase of a one-liter bottle of 151-proof Demerara rum on the evening prior to flight.'

More keystrokes, and the receipt was replaced by several views of a charred canvas bag.

'The Lindenbaum bag and its contents, and these objects alone, of all the artifacts recovered from the crash' — the phrase emphasized by a hard look to the audience

— 'manifest geometric burn patterns showing symmetry and more combustion inside than outside.'

He traced the patterns with his laser pointer.

'Interviews with family members have disclosed that Walter Lindenbaum was a pipe smoker. He was of the habit when entering a no-smoking area of slipping his pipe into his pocket and relighting it later. Al evidence points to the presence of a smoldering pipe in the pocket of the Lindenbaum jacket when that jacket went into the cargo bay'

A murmur spread through the back of the room. Hands shot up and questions were shouted. Jackson ignored them as he projected additional pictures of burned clothing, unfolded then folded.

'Inside the baggage compartment, fragments of smoldering tobacco and ash spiled from the pipe bowl and communicated incandescent combustion to surrounding fabrics in the bag, generating what we cal a hot spot.'

More shots of burned canvas and clothing.

'Let me repeat. Geometric burn patterns have been found on no other items recovered from the wreckage. I'm not going to go into it here, but the press release explains how evidence of slow burning of folded clothes inside the bag cannot be explained by anything that occurred after a midair explosion.'

The next visual showed smoke-blackened fragments of glass.

'Mr. Lindenbaum's rum bottle. Inside the loosely packed duffel, smoke spread at a temperature consistent with that of the localized combustion, a temperature warmer than the bottle and its contents, which were not involved in the combustion process. The bottle remained intact, and smoke was deposited on it. These deposits, seen in this view, have been analyzed by our lab. The products of decomposition present in the smoke are consistent with the point of origin as I am describing it. Traces of tobacco smoke were positively identified on the bottle, among other traces, especialy since forensic analysis also disposed of unburned tobacco strands in the pipe bowl as reference.'

Jackson switched to a diagram of the plane.
