this because angus houston, the man leading the search coordination effort, he said clearly in a press conference that they are going to search with the tow pinger locator. they re going to search for that ping absolutely no chance until there s no chance that the devices are still transmitting. how long does that continue, do you think? how long do they keep hope alive that the device is still transmitting? well, as we ve all said before, that, you know, 30 days is what the from a regulation standpoint required to be active. typically go beyond that. typically once we get out to around five or seven days beyond that, so around 35, 37 days, then we re starting to think that even though every t battery will be a little bit different in its capabilities, probably by that point in time we ve exceeded pretty much 99.9% of all the batteries out there.
