Who are you gonna believe, Boeing or your own lying eyes?

Boeing Co. (BA)'s assertion that U.S. investigators ruled
out a fire within the battery case of a Japan Airlines Co.
(9201) 787 is premature, a National Transportation Safety
Board spokesman said.

Investigators examining the Jan. 7 fire aboard the
Dreamliner in Boston haven't ruled out that flames erupted
within the lithium-ion battery container, Peter Knudson
said today in response to questions about the issue.

Michael Sinnett, Boeing's chief project engineer, said in
the briefing that investigators hadn't found evidence of
flames within the Boston battery's container box, an
indication it worked as designed to limit damage from a
battery failure.

A witness who tried to fight the Jan. 7 fire said he saw 3-
inch (7.6-centimeter) flames outside the lithium-ion
battery, and the NTSB has found evidence of high
temperatures within battery cells that failed, according to
preliminary safety-board documents released March 7.

Gawd ... is THIS thread still going on ???????????/

Yes, the 787 is a failure.

Put it this way ... after hearing about its problems *I* will
NEVER fly on one - ever.

And I'm hardly the only one who feels this way.

Not interested in burning to death over the Pacific ....

The conventional Batteries are sometimes called Sealed Lead Acid
Batteries but they are actually AGM batteries.

Modern passenger aircraft normally use Nickel Cadmium batteries

Less time between
replacements, requires a heated and cooled area but is the most
dependable. If that is all that is keeping the 787 from flying, it's
a pretty simple fix.

Not necessarily as that may need recertification which is a complex and
lengthy since the batteries would be heavier and take up more
space.
