When I was a proby in E5, there was a member that was a proby at that fire. He was instructed to remain at the top of the stairs, as the rest of the company entered the cellar. After a short time, he observed papers and debris being sucked down the stairs. Not sure what was happening he shouted to all members to get out of the cellar. As at least 2 companies L3 and E5 raised up the stairs as the fire roared over their heads. He saved many more from sure death. Unfortunately he is no longer with us. RIP to all!
