 The sailors at NMC displayed their effectiveness at moving large and dangerous ordnance using the vertical launching system, or VLS, for their bi-annual certification. Aviation ordinance been third class Sarah Pressin understands the importance of doing her job correctly and keeping up to date on certifications. Getting me certified is important because just so that we know that we're still doing the same thing that we do every day but we're doing it properly and safe. You don't want to get too complacent. When you have a missile that's worth a lot of money and you just don't want to gamble something like that. Communication and safety come first to Gunners mate first class Billy Hawkins as he keeps a watchful eye on his team as they perform this evolution. Communication is essential with anything that you do, especially more so handling ordnance. One rock step, one rock movement and somebody could be gravely injured. While he is aware of the risk Hawkins trusts his team and the training they have received. From Naval Air Station Siganella, I'm Seaman Luke Askew.
