Flight Level, yes, is in hundreds of feet e.g. "Descending to Flight Level 280". However, it is not actually altitude (distance above mean ground level) but measured using a standardized pressure setting on the altimeter e.g. 29.92 Inches of Mercury or 1012.25 Hectopascals (used to be called millibar)
We also use Knots (nautical miles) for speed because of their relation to one minute of arc along any great circle.
I grew up with feet and inches, pounds, shillings and pence - ha-pennies too. I don't know my height in meters, and I don't much care to either. Never the less, I appreciate and use metric scales of all sorts in my daily life and I get by. I am sure anyone needing to use different scales from the ones they are used to will be sanguine and adjust accordingly.

Lets get the terminology right:
Passengers are actually Self-Loading Cargo.
Passengers are loaded into Cattle Class no matter how much they pay for their fodder.
Passengers are treated like toothpaste - forced in at one end, squeezed out at the other end.
Height is distance above ground (dirty brown stuff,)
Altitude is distance above mean sea level (dirty wet stuff)
Auto pilots were made so that Captain Speaking and First Officer Here (heroic chaps!) could check their stock options and give peace of mind to the Trolly Dolly - Cynthia Strapin, that for at least some portion of the flight the aircraft was actually under proper control.

I for one salute the brave, bold, adventurous, noble souls that want to go to the edge of space and have a peek, but I would rather spend the time in a broken down elevator with late '60s muzak and a herd of incontinent goats.

Comment What an Idiotic Design Concept (Score 2) 76

Please bear in mind that 'Water, for all intents and purposes, is an incompressible mass.' We teach this to student divers.

Look at the following points...

Fore-planes - they are curved and cannot act in an 'aerodynamic' manner (wings create lift by causing air to reduce in pressure as the air moves in a longer path over the wing than under it,) so they are really just flow directors, and the curves will create permanent turbulence and disrupt flow behind them - the forward vertical thrusters.

Forward vertical thrusters - turbulent flow will create beta on the blades (uneven flow vectors to different blades) destroying efficiency. The fenestration/cowl that surrounds the thrusters will cause turbulence also.

Forward hull - the hull immediately around the area of the forward thrusters is voluminous and bluff to the flow of water when under way. Turbulence and drag will ensue, and this will run toward the stern gear - thrusters, aft planes, pusher thrusters and elevator.

Stern vertical thrusters - similar flow conditions will exist for these units as they exist for the forward units.

Pusher thrusters - will receive all turbulence created by gear that is forward of their position, and reduce efficiency accordingly.

Elevator - single piece curved flow director, similar to the fore-planes in intended down-thrust effect. Same problems of turbulence and drag. Potential for anti-asynchronous oscillation from turbulence caused by all equipment forward of its position.

I saw the previous version of this craft, the Super Falcon, when it came for a demonstration in Jordan in April 2011, and was unimpressed with what I saw. This concept version is not an improvement. They should get proper designers to work on it, not people that just happened to see an aircraft, or read a few pages of Wikipedia.

Yes, a new species conflict would ensue if you took away the humans and left the rats, cats, dogs etc.. But I see you only want to take the humans out of the equation... Leaving the Lawyers (mutant species already in place) to fight the rats, cats, dogs etc.. That would be so cruel on the rats etc.. Perhaps Mothers-In-Law would equal the fight?

Could this be given to terminally ill patients so that they get the gift of a life time of wonders without all the blisters of from trekking, early mornings, hangovers, late nights, working life, lousy bosses, mosquito bites, etc..
Just imagine being able to gift a full-life world holiday to someone: Machu Picchu, Tierra del Fuego, a life of diving the greatest reefs, gliding the Andes, kayaking the Colorado.

I would have expected someone to raise the possibility of insurance companies mining the information so as to avoid dealing with 'problem' medically compromised customers, or at least increasing the coverage fees to unacceptable levels and thereby driving off the 'problem'. Perhaps that potential new employer wants to know that you aren't medical damaged goods? Perhaps you have to apply to the police or a local authority for permission for something, and they want to use the medical records to check your suitability/mental condition/drink/drugs etc..

I would have expected someone to be making comparisons to 'Gattaca' by this point in time.

Almost every day I dive past one of the Smithsonian biomass accretion modules in Aqaba Marine Park, Jordan. You can see one of the collection modules here.

If only academic departments/institutions collaborated or communicated a little bit more, maybe the research dollar would go a little further?

Instead of using words, how about playing the keyboard as if it were a piano (or any other keyboard-like instrument)

Here is an example of a musical login: pvy89pvvv[890[]vv

For this example, position your right hand with the thumb on the 'v' key, then play the sequence as if they were notes, then listen to C.P.E. Bach - Minuet In G Major for what it should really sound like.
