Being from the Detroit area, I find many of the comments here naive as one can't compare Detroit to an average urban city. To understand what Detroit is like, watch a film like "Escape from New York" or a WW2 bombing document

The money is there - $250 million per year for social workers alone in SF and increasing ... The will to build a single unit of housing for homeless people isn't though.

TLDR; 11,000 words of gossip about GE CEO promotions with no insight into the actual business problems. Makes the authors look like incompetent wannabe "journalists."

Airplanes always get most of the energy from ascent back in descent. VTOL will get less back because it's grossly inefficient. Note that drag needs to be deducted from the potential energy. There's parasitic and induced drag.
