00:00In the early hours of the morning, the mountain delivered its killing blow.
00:04The eruption column collapsed, and a pyroclastic surge, a cloud of superheated gas and ash,
00:10raced down the slope at hundreds of kilometers per hour.
00:13It hit Pompeii like a wall of fire.
00:16Scientists now believe the temperature reached 300 degrees, hot enough to kill a person in a fraction of a second.
00:23There was no time to run. No time to scream.
00:26The heat was so extreme that it vaporized soft tissue, and in one victim, researchers found something almost impossible.
00:34Rain tissue turned to glass by the heat.
00:37A human brain vitrified like black glass.
