Other mistake: When the strike aircraft is on approach, the pilots ask the tower for a Precision Radar Approach. The air traffic controller confirms it will be a PAR, not a PRA.
Suggested correction: This has previously been commented on and corrected.
Stupidity: If Guerrero had limited money and wanted to be sure to blow up the plane over water, he certainly could have bought a ticket to a much cheaper destination than Rome, such as a Caribbean island.
Suggested correction: "The North Atlantic leaves no traces." He wanted to down the plane where recovery and investigation would have been practically impossible.
Other mistake: When they are trying to put together the character of the potential bomber, when he bought insurance, the woman who took his details said she remembered him because he didn't seem to have much money for someone going to Europe, but the bomber had told her he had changed all his US money for Lira, and when she persisted, he said the money was all in big bills, and he had left his cheque book at home - so he did have money.
Suggested correction: He said he did, but we know he didn't,, and anxious as he was, he was a terrible liar. The insurance gal saw right through him. Clearly, no talent for either insurance fraud or mass murder.
You might also take into account that in those days 10,000 Italian Lira was worth a measly US$5.69, so having nothing but "big bills" - large denomination notes - would not have been difficult.
