The following is a transcript of the cockpit voice recorder aboard United Airlines Flight 93. All times are in Eastern Daylight Time (Irish time minus 4) on September 11, 2001.

US Federal prosecutors seeking the execution of Zacarias Moussaoui figuratively placed the jury aboard doomed Flight 93 for its last searing moments, playing a recording in which the September 11, 2001, hijackers were heard ordering passengers to “shut up” and “sit”.

Prosecutors approached the end of their US death-penalty case against September 11 conspirator Zacarias Moussaoui after a gruelling week of testimony about the appalling impact of the September 11, 2001, attacks on victims and their families.

Jurors weighing the fate of September 11 conspirator Zacarias Moussaoui viewed gruesome photographs of bodies burned inside the Pentagon and heard from two determined military officers who crawled almost blindly to safety through falling debris, choking smoke and searing heat.
