First, about the battered but durable small-airplane, point-to-point travel movement, chronicled frequently over the past ten years (
here, for starters), a retrospective from Bruce Holmes, long time "extrepreneurial bureaucrat" from NASA. Holmes was one of the three heroes of my 2001 book
Free Flight and later a force behind the promising-but-doomed company
DayJet. (Below, Holmes a few years ago, in a NASA photo.)

Holmes recently returned to his NASA-Langley stomping grounds to give a basically positive "lessons learned" discussion about the DayJet experience. Brief article about his presentation
here; his summary below.
[DayJet] was a case of "the operation was successful, but the patient died,"
but it was only a start, Holmes said. It was a glimpse into an aviation
future in which, he added:
--"We need to get to carbon neutral (aviation operation),
--"We need to halve the operating cost and
--"We need scalable airspace capacity."
Godspeed on all fronts.
Second, about the
unresolved question of why the Air France 447 crew found itself in the middle of a powerful thunderstorm, this from Bill McHugh, a private pilot in Louisiana:
You may or may not remember some years ago that a
737 flown by TACA Airlines made an emergency dead-stick landing on a narrow
levee near the NASA Michoud facility in eastern New Orleans (Google "taca
airlines levee landing"). It had lost both engines due to hail ingestion while
flying through a severe storm on approach to MSY [the main New Orleans airport]. The landing was successful,
with no loss of life or injuries. The captain was hailed as a hero by the
passengers and in the press (frankly, I was more impressed by the Boeing test
pilots who got the thing back off the ground a few days later).
A couple of years after the incident I was
attending one of those FAA safety courses at NEW [New Orleans Lakefront airport]. This course was about weather,
and one of the speakers was a guy who had worked the NEW and MSY towers for
many years. He told us that he had been working the tower the day of the TACA
incident, and that he had personally warned the TACA captain no less than three
separate times that the storm ahead of him was severe (can't remember what level
it was, but it was high) and that it probably contained embedded hail, but
that the captain had ignored the warnings and had flown directly into the
storm.
Point of the story: Even seasoned, professional
pilots do stupid things on occasion.
