Kiwi documentary maker Rob Harley was one of the first journalists to get close to the Texas fertiliser plant after the explosion.
Harley, from Auckland, was in a hotel in Waco, 20km from West, when all hell broke loose.
He was filming a documentary about a Kiwi woman, Grace Dominguez, who escaped the clutches of Branch Davidian cult leader David Koresh, but lost her sister and other relatives in a fire that killed many of his followers in 1993.
