Neat it's almost like they are trying to develop these...

What they are doing is collecting flight data on unusual maneuvers/attitudes that no one, well the engineers and corporate bigwigs would never allow with allow with the real jet. Long gone are the days when a Boeing test pilot
rolls the prototype 707 to show off for potential buyers.

look here

Can you actually scale a plane like that down to that size and get reliable data back?
Comment by Greg Fletcher on June 29, 2010 at 8:50pm
Yes they can. Aeronautical engineering guys know how to scale the Reynolds numbers, mass and speed and all that good stuff. I thing they just keep the Reynolds number the same for full scale and model. The speeds would be reduced according to the formula here

Spending all that money on augmenting a pilot's control instead of making everything autonomous sounds like FAA influence.

FAA influence is trying to keep giant flying beer cans full of people alive. Don't discount human pilots. Although they do lock up some times, their systems are very robust.

That Mobile Operations Station looks some serious piece of kit. I don't think my wife will let me convert the campervan.

You woont be able to keep the Reynolds number for a model wing that size the same as a full size - unless in lab conditions. The airfoil section will not be a scale as it would stall at very low AoA

If the wing chord reduces by a factor of 10 (ie a 1:10 scale model) the model would need to fly at 10 times the speed of the full size aircraft, which would make that a supersonic model!!

but why did they make the paint scheme so ugly ;)
