Reminds me of an incident years ago with a commercial flight on a late night approach to Nice Côte d'Azur Airport in France. The crew apparently lined up on the bright sodium vapor lights of a main boulevard several miles from the airport. At about 1000 feet, the crew realized their mistake, aborted the landing, poured on the power, and then did a low altitude go-around, hedgehopping over the rooftops of downtown Nice, waking up and scaring the merde out of much of the city.

And also the loss of the Mars Climate Orbiter probe due to an error in acceleration data between the JPL navigation team, who used metric distance units, and the probe designers at Lockheed that used English distance units.

An unbiased, objective assessment by a co-founder, CEO, and stock option holder of an autonomous flight startup company? I don't think so ...

What are the technical merits of Boeing's criticism? Did Boeing do a risk assessment? Does the severity of the risk include loss of the aircraft? Many safety-critical industries regularly trade information on hazards among competitors. In medical device design, this sharing of information is actually mandated by consensus standards that guide safe product development. We routinely incorporate lessons learned from other manufacturers in design mitigations that reduce risk and increase safety. I hope that Boeing is not dissuaded from performing this important role in safe aircraft design.

Mr. Bastian is free to run his airline the way his stockholders want. The flying public is free to choose the airline they want to fly with.

Skipping a checklist is not a "mistake". It is hazardous risk-taking with potentially catastrophic consequences. Northwest Flight 255, with a combined 29,000 hours in the cockpit, still haunts me.

Hugging my pig got me through this devastating news.

I commuted every week on the first flight of the day of a PSA Electra in Tahoe service. That early morning first leg was from LAX to OAK. My favorite memory was the engine startup after being parked overnight -- the aircraft interior was lit up with an orange light from the 10 to 20 foot flames shooting out of the turboprop exhaust! It always got a little yelp from the newbies on board.

Might be the increased risks in lithium battery technology of self-ignition and thermal runaway. Once an aircraft design has incorporated nickel-cadmium NiCd battery technology, it is a major design change to convert to lithium, including going back to the hazard analysis and ensuring that additional risks have been mitigated. Lithium battery technology should only be employed in an aircraft design when its weight-to-energy advantage is essential. And the mechanical packaging, the more complex charging circuitry, and temperature monitoring must all be carefully designed and validated for safety.

I went to the Harvard T.H. Chan School of Public Health website. Found a note about this on-going research, but no report. Has anyone else found the report? I'm VERY suspicious of this "1%" statistic.
