@dr_boese Bei Fluzeugstau sind immer beide (oder mindestens ein) Motor ausgeschaltet. Ist also nicht so schlimm.

Man stelle sich einmal vor, wieviel Kraftstoff hier vollkommen sinnlos verheizt wird. Dazu läuft noch teure Triebwerksbetriebszeit auf. Dass es dafür keine andere Lösung geben soll, verstehe ich nicht.

@LauraSavino747 @MCCCANM It’s hard to watch the left engine breaking off. We did not think that the same issue from 1979 would happen again, but it did. ntsb.gov/investigations…

@PatrickGr @MCCCANM That makes no sense.

Being told a UPS MD-11 has crashed in Louisville. No more details yet. Hope the crew is safe… I have many friends that fly the MD-11 after flying the KC-10. It has a few quirks.

@LauraSavino747 @MCCCANM A detaching engine makes this more like AA191 in 1979. In this case there seems to be less asymmetric lift, so the left slats and flaps likely stayed out. But the remaining two engines somehow could not lift the airplane in the air.

@MCCCANM Uncontained engine fire... still had two good engines. Looks like the fire burned through the wing. Eerily similar to the Concord loss.

@LaurenGoode It is the 9th anniversary of the U2 iPhone 6 debacle, and already the 19th anniversary of the special U2 edition of the iPod.

Another Apple event has come and gone and I just have to say I’m still mad about U2

@giulio_mattioli The per-person-per-km GHG emissions of an airplane are about the same as a city bus or a car. Electric trains are better. This is based on the emissions current US energy mix and diet.

[as some have pointed out in the replies, GHG emissions pkm from cars can be equivalent or higher than planes depending on the vehicle, the country, vehicle occupancy, and whether radiative forcing is considered so the survey question is a bit clumsy]

This confirms that the public don't know how carbon intensive air travel is. Only about half of respondents in high income countries correctly answer that the "GHG footprint of plane is higher than car or train/bus". Just 41% in the US! cleanenergywire.org/factsheets/sha…
