 Any radio, this is down to aviator, how copy? SAR is a search and rescue. So when a jet goes down, we have to be able to find that aviator and then go and pick him up. Actually seeing the jet come in overhead and talking him on to where I am, so it was easier for me to see him and tell him where I was and watch him come around and actually be able to find me and then give that location on to the helicopters. Training is really important because the mixture of the aviation fixed wing and rotary wing, getting eyes on and down to aviator and getting to rescue, having him pulled out of the water, it could be the difference between life and death.
