The story
making headlines on the anniversary of the disappearance of Malaysia Flight 370 is the news that the battery for the locator beacon in the plane’s
flight data recorder was not changed on schedule as it should have been. This
raises the possibility that one of the plane’s two black boxes may not have
been emitting an audible signal for searchers to have picked up.
Failing to replace a dying
battery and the consequences of such a lapse is a scenario everyone can relate to, which is why this particular revelation is big news, even though it is exceedingly unlikely that the towed pinger locator was ever within a few miles range of the missing Boeing 777 in the first month after it disappeared.
