couldn't have put it better myself, times and technology are changing and we as SAR Operators have to go with the flow
No, you don't have to go with the flow. You embrace new technology if it helps you to do the job but you make sure it is properly trialled and tested before you implement it. Perhaps the Coastguard should have tested the Sat Comms with a HF radio as backup. That way the S92 might have had proper Comms with them.
But to go with the flow because its new and therefore must be better is totally wrong. The Coastguard should have checked the system worked before risking the SAR crews who do the job.
