787 Batteries and Chargers - Part 1

[RR_NDB]

We technicians cannot (or should not) say IMMEDIATELY everything we learn?

Hi,

From the info we have, it looks like the charger's led display provides the
equivalent of car's dashboard "idiot lights", which won't be necessarily be
that helpfull to investigators.

FX: Message from Charger, "battery has failed". Fireman: Yes, thanks for that,
we just finished putting the fire out

The above is standard technique all over industry, so why not this charger ?...

This question will be answered by a serious govt. investigation or by a Richard Feynman style work made after Rogers commission Challenger SRB failure (also temperature related )

Feynman's account reveals a disconnect between NASA's engineers and executives that was far more striking than he expected. His interviews of NASA's high-ranking managers revealed startling misunderstandings of elementary concepts. For instance, NASA managers claimed that there was a 1 in 100,000 chance of a catastrophic failure aboard the shuttle, but Feynman discovered that NASA's own engineers estimated the chance of a catastrophe at closer to 1 in 100

The commission members were Chairman William P. Rogers, Vice Chairman Neil Armstrong, David Acheson, Eugene Covert, Richard Feynman, Robert Hotz, Donald Kutyna, Sally Ride, Robert Rummel, Joseph Sutter, Arthur Walker, Albert Wheelon, and Chuck Yeager.
