Cool Photo From Germany...

No, I won't use the "N" word here (rhymes with Yahtzee) as that just brings up all sorts of ugly feelings and makes people think that one is promoting a certain political or sociological agenda.

I just have a fascination with aircraft, militaria and technology in general and thought this was a cool photo.

You have here a Messerschmidt BF-109 undergoing wind tunnel testing.  It always amazes me how advanced some things were some 80 years ago, yet so undeveloped at the same time.  Nowadays this would all be done in a computer or at the very least, in a computerized windtunnel.  With this photo?  Maybe they used high speed (film) cameras and pieces of yarn to try and get an idea of the flow of air over a vehicle.  Lots of slide-rulers and pencil and paper were expended that's for sure.

I also enjoy seeing photos like these as in my minds eye, historical vehicles just kind of appear on the scene and I don't think about all the infrastructure, time, testing and calculation that went into their development.  Seeing one such famous airplane in its build/testing phase just seems kinda cool--as does the scale of the huge windtunnel vs. the airplane itself and the little engineers below.

SpaceX Grasshopper Test Video

SpaceX continues its march forward.

While its commercial flights servicing both governmentall and private business demands via its standard launch systems it is also working hard on its Grasshopper program which will eventually (hopefully) result in a completely vertical take off and landing program designed to return the launch vehicle to its launch site autonomously upon completion of its mission.

SpaceX has been ramping this program up bit by bit with short test flights.  This most recent test took the Grasshopper up to 12 stories and then returned to its platform.  Its funny to watch as at any moment I expect the rocket to turn sideways and explode as was often the case with many Nazi and Soviet (and a few US) launch attempts when they were first starting out.  It almost seems unnatural for a rocket to not either shoot skyward or else end in disaster.  Watching it land on its gear so softly and without a fuss is an odd thing.

The ability to return to its launch facility in this manner is designed to cut costs and increase the speed at which launches can occur--a necessary step for sending large amounts of equipment, supplies and people to Mars.
