Hi Bazz

Ocean Shield detecting four sets of pings (including two sets of pings yesterday) in one area is promising.

If they actually find the aircraft on the bottom then retrieving parts and bodies will likely take years.

On whether aviation and broader safety authorities should require upgraded technical functioning of pinger transmitters, it might depend on:

- the results of multi-year inquiries following this MH370 event

- the rarity or otherwise of events like MH370

- the cost of replacing or upgrading transmitters and whether users would generally accept this cost. This is including transmitters for dinky little light aircraft.

- whether pinger receiver equipment needs to be upgraded to detect new style transmitter characteristics.

- whether Safety is the same issue as Recovery of aircraft parts and bodies

Overall, as in car safety, authorities accept or organise a compromise between improved safety and higher cost.

Well as to whether safety is related to recovery, unless you get
recovery you cannot find the cause with any certainty.
As far as cost is concerned, how much is this search costing ?

Lots.
