Yes, Chuck, it has stalled because of the sound barrier. If a plane exceeds the sound barrier from the West Coast to the East Coast, the sonic boom is heard across the entire nation. Everyone below hears the boom. NASA is working on eliminating the boom. That's what it would take.

TJ, I'm surprised you haven't gotten more responses to your post – it hits the status-quo method very hard, and airline execs would cringe in light of the truths you profess.  One similar technology scenario comes immediately to mind, and how new developments attempted to overcome it. 

I'm referring to the component placement process for PCBs.  Conventional process, currently used in millions of manufacturing facilities world-wide, uses the well-established "Chip-Shooter" method to place components plucked from tape/reel packaging, and robotically maneuvers individually components into precise location on the PCB while held by vacuum.  But most sophisticated products have literally hundreds of components on their main board, so this Chip Shooter technology, while EXTREMETLY FAST and ACCURATE, still places them one at a time .... Like passengers on a plane going thru the front port-side cabin door.

The developed counter-solution to this was GANG-Placement technology, where literally scores of T&R components were dumped (a large gang batch at a time) thru a Z-axis filter, similar to the way the solder stencil was used at the front of the line, hitting all locations simultaneously.

Several big-name electronic giants (MOT) experimented with this technology several years ago, but I think the dream remained largely UN-realized;  and so today the Chip-Shooter still remains the De-Facto Standard for  solder component reflow automation in the world today.

I submit that passenger seating and dis-embarking would fare much better, using the simple, obvious suggestions which you've outlined. Kudos to your common sense.

Air Forceís (Lack-of) Plan for recovery

After reviewing this article and the several dozen comments posted, I'm surprised no-one has reacted to the Air Force's (Lack-of) Plan for recovery.  To me, this is a design flaw from Square-One.  If the cost of recovery exceeds the value of the development;  well ,,,that speaks volumes to the cost of bureaucracy in the military today. Literally, flushing the experiment away, available for recovery by other salvaging interests.  Really-?

Thanks for a great explanation, Bill. Actually, I'm okay with longer flight times. If it took 60 minutes to fly cross-country, I'd probably be jumping on flights every week. This way, I get to stay home more.

I recall as a kid growing up in Chicago during the Cuban Missile Crisis, supersonic defense jets would fly over Lake Michigan, rattling the windows in my second grade classroom. Sonic booms can indeed be disturbing.

Air travel at fast speeds.

Batar is certainly correct about the cost and viability of high speed flight. And, even more important than those sad economics, is that fact that air transport is still hamstrung and slowed by our "security" people, who are a huge waste of resources and a questionable value. They have certainly been able to make airports much less enjoyable than the second day of old aArmy basic training. So if one still needs to be at the airport two hours in advance of ones flight, the advantage of turning a two hour flight into a 15 minute flight is not so great any more.

It would be far more useful to research toward development of some form of matter transmission, which could happen at nearly the speed of light. THAT would be a worthwhile increase in speed.

I remember them, too, when I was a kid in the early-to-mid 1960s in Michigan. The boom was huge. I always enjoyed them in a kids-like-adventure way. But they really did rattle the windows and they were a shock to the system.

You raise a good point about the security issues, William K. Every flight involves at least two extra hours on the front end and at least 30 minutes on the back -- and that's if the flight is on time. So, yes, there would defeinitely be an issue of diminishing returns if you change your Chicago-to-Detroit flight time from one hour to 15 minutes. You'd still have to waste a minimum of two-and-a-half hours at the airport.
