US Grounds Boeing 787, The Anatomy of a 20 Year Denial, and a Bubble of Self-Confidence

An almost sad tribute to Boeing’s 787 above, attributes the recent Infernal Batteries problem of two 787 a week apart from each other, both while in normal operations, to the growing pain of “innovation”.

Except, this was not “innovation”.  Using such batteries in airplanes perhaps, but the battery technology, Lithium Cobalt Oxide type, is not new.  It was invented in the late 1970’s, and have been in prolific use in cell phones and laptops since 1990’s.

Back in the early 2000, there began rumors around the world of incidents where cell phones exploded.  First, it became an urban legend attributing such explosion to sparks generated by an operating cell phone near a gas refilling station.  But this was quickly denounced as “urban legend”.  https://canadasafetycouncil.org/safety-canada-online/article/cell-phones-risks-and-rumour

COMAC C919 gets 100 orders

COMAC C919 orders signing ceremony

Six months ago, I wrote about the “COMAC C919, Challenging the Boeing and Airbus Duopoly.” The aircraft was scheduled for production release in 2016. And looks like the plan is proceeding well. The company has reported 100 of the planes having been pre-ordered by various airlines. So, here we are, six years before release, the C919 has already started making dents in this lucrative industry.

You may follow the above link to see who the suppliers are (for various subsystems of this aircraft) as well as other pertinent information about the market the C919 competes in. The C919 leverages COMAC’s experience from the ARJ21 which is expected to enter service this year.

The orders are making news around the world. Additional coverage by USA Today: “China wants to rival Boeing, Airbus with its C919 ‘big plane’.”
