I was not aware that they put the scoop on NA models. What is the purpose of the hoodscoop on those?

See my reply to Turbineguy http://jalopnik.com/5974158/?post=55985476. Even though the airframe is moving at less than the speed of sound, airflow over the wing is moving faster and approaching the critical mach number http://en.wikipedia.org/wiki/Critical_Mach_number. I can't remember the book, but IIRC at altitude…

I know I'm a day late on this, but figured I'd chime in. The U-2 at altitude operates in the "coffin corner" http://en.wikipedia.org/wiki/Coffin_corner_(aviation) of the performance envelope. I can't recall the book, and can't find anything with google at the moment, but IIRC if the U-2 turned with too tight of a…

It takes more than two... to tango!

For props to counter-rotate there must be at least two? No?

You might say they are... car flambe.

You'd best not let anybody get inside your OODA loop.

Could have been even better if they had paid more attention to John Boyd. If you want an interesting read, try this: Boyd: The Fighter Pilot Who Changed the Art of War. It is an excellent book about an impressive pilot.

I must see photos as proof of this.

Sure, there is risk to using hydrogen. But if you look at a risk benefit analysis maybe it is time to revisit hydrogen as the basis for lighter than air travel. There is a shortage of helium which while extremely stable is also rarely found in nature. Plus using hydrogen will just about double the lifting capacity…

Is hydrogen really that unsafe to use in lighter than air vehicles? If the gas envelope is filled with hydrogen and no oxygen is present there should be almost no risk of a fire. If the envelope is actually impermeable and made of flame retardant material and proper precautions are used, would a hydrogen airship…

Looks like SAAB's proofreader wasn't very good at math "...standard in both the Saab 99 and 95 and 96 models..."

What is your favorite surface to race on, tarmac, gravel, snow?

Was never inside it though we did ski above it. The concept of an airport on the side of a mountain is just awesome.

Go work at a UAW plant as an hourly worker and don't join the union. Let me know how that works out for you.

Actually Michigan is a "closed shop" http://en.wikipedia.org/wiki/Closed_shop state, so you do have to join the union to get a job in a union shop.

You tell me. The rank and file get screwed over while Bob King and the guys heading the union get rich. Sounds like what they're going for. Or at least what they are achieving on accident.

I don't know how it is inside the airport, but when you're skiing Courchevel airport makes for some interesting viewing. It isn't high traffic or anything, but trying to get your head around how they managed to build an airport on the side of a mountain can entertain you for quite a while. And actually seeing a…

So it bothers you when people have to go to the ATM machine and can't remember their PIN number too doesn't it? For some reason that just grates on my nerves too.
