AF Accident rate

Two points:
1. Arbitrary start date, 1988, moves Habsheim crash into the 1988-2009 period.
2. Wikipedia page says AF had 3 fatal hull losses in 1968-1969

pinger life/search resources

tekata: trouble is, that's 3 ships that are appropriately equipped (by my count), plus some odds and sods (frigates? submarines?) which won't be able to contribute much. Very difficult to make an...

Phil Gollin - FDR/CVR search & recovery

I don't know about the status of the search, or about the 'true' battery life of the devices. Other people have commented on these issues. I used to work in the hydrographic survey industry, so I can...

You can extend the battery life very easily by reducing the ping rate most of the battery power is expended in putting acoustic energy into the water.
