 Down through the lifting provision, one time and one time only. So today we're actually conducting sling load operations, which is phase two of aerosol school. For the last two days they've been learning how to prepare and rig and actually inspect the four loads that we have here behind me. So things we teach them to look for, things like incorrect link counts, incorrect material, securing one thing to another. Anything that could cause this load to either lose stability or even worse fall from the aircraft while in the air. So far today we've finished up with our classes. Now this is actually the meeting and the grind of phase two. They're actually getting on the loads. We get to see how they look during their inspection sequences, get the help students out and need help. When they leave here they become certified sling load inspectors. If their unit's conducting a sling load operation, they're actually able to inspect the load once it is prepped and rigged and certified to put it on a bird. It's good training that they can have, helps set them up for their careers furthering in the future.
