 If you know much about WWII German aircraft technology, you probably already know that they were pushing the design envelope in ways that are truly hard to believe.  I know I never get tired at looking into the minds of the people that came up with so many amazing aerodynamic ideas.

 On Sunday, June 28, the National Geographic Channel will air a special program that looks in-depth at the design of the Horten Ho 2-29 flying wing.  This aircraft is quite possibly the most extreme example (that actually flew) of the amazing aviation thinking that the German engineers had near the end of the war.

 BTW, this is just the kind of TV programming aviation people need to support... you can do that by simply watching and enjoying, so don't miss it!

 The Ho 2-29 design that brothers Reimar and Walter Horten came up with was not only a quantum leap in aerodynamics, but also appears to have stealth technology incorporated into both the shape, and the use of wood on the skin.

 This interesting and well produced Nat Geo special explores the possible stealth nature of the aircraft with, of all people, Northrop Grumman!  They actually built a full scale model of the beautiful flying wing to test it's radar signature on a 50' articulating pole.

 It's fascinating to see the American company that built flying wings in the 40's, and then built the B-2 Stealth Bomber in the 80's, as they marvel at the amazing design of the Horten brothers flying wing.  Be sure to catch this program, you're gonna like it.

This Is How You Fly A B-17!

 This video is just a minute and 16 seconds long showing a really great airplane, a B-17, being flown in a really great manner.  What a fabulous example of a textbook landing!

 When I was just 13, my dad was unofficially teaching me to fly in a brand new 1973 Citabria 7KCAB that he'd just bought (he wasn't a CFI, but he was a great teacher).

 I remember that he taught me something very simple that can really make a big difference.  It was just this: make the airplane do what you need it to do, whatever it takes to make it happen.  It's the difference between mostly going along for a ride, and truly being in control.

 This landing shows what it looks like to be in control : )

Have You Pull-Started Your 'Me 262' Lately?

 Maybe this pic doesn't strike you the way it does me... but a guy pulling a handle on a rope that's attached to something inside the engine on an Me 262 definitely makes me go, hmmm (out loud). 

 Let's back up a minute here. Since my dad passed away recently, I've been going thru boxes of stuff he'd accumulated over the years.  In a recent box, I found a 2 DVD set from 2007 titled ‘Flight Check Fighters' - ‘The How-To-Fly Series' that's available from TimelessVideo.com.  These 2 DVD's have tons of actual footage from military training films that show you about everything you need to know to properly fly the P-38, P-39, P-40, P-47, P-61, and the Me 262.  It's a great set that you should seriously consider adding to your collection.

 It was the Me 262 that caught my eye on the package right away.  So I tossed the DVD in the computer and start watching an actual German training film on the first jet aircraft to go into service in WWII. Cool stuff.

 I'm just watching away thinking this is pretty amazing to see (and I'm thinking, wow, the crazy mechanical nightmare that were the aircraft from that era!).  After a bit, an instructor is showing a student about the throttles and engine controls when a third guy walks up and grabs a handle on a rope located right at the hole in the bullet in the middle of the nacelle. Then, he starts yankin' on it!  I'm thinking, what the heck?!  Is this some kind of crazy pull-start pre-rotator for the compressor? What in the world is he doing?

 Well, my friend ‘Mr. Google' helped me out... and I found out something very interesting.  Seems the Germans engineered a small 10hp 2-stroke 2-cylinder gas engine into the nacelle to use as the starter for the turbine when a ‘cart' wasn't available!

 So, the guy is actually pull-starting that little gas engine, which then spins the compressor enough to fire up the turbine engine.  I think that's just cool, crazy, and topped off with more cool! I never knew the Me 262 was really a 4 engine, turbine/2-stroke hybrid!  Also very interesting to note that these early turbines had a TBO of only about 25 to 50 hours!  Ouch! 

 The upper picture above shows a 2-place version of the Me 262 from the Delaware Valley Historical Aviation Association Museum in Horsham, PA.  This beautifully restored aircraft makes it easy to see the pull ring in the center of the nacelle, and the 2-stroke is nestled inside the 'bullet'.   

 The lower pic is from the Air Victory Museum in Lumberton, NJ and shows the little Riedel 2-stroke engine on the front end of a Junkers Jumo 004 engine (with the center ‘bullet' removed).  Apparently this 2-stroker could be started from the cockpit via electrics, and the pull start option was for back-up. The large 'pull' ring is clearly visible here.  Looking close at the 2-stroke engine design, and the compressor blades behind it, it's fascinating to see how little has changed in 65 years.  Materials and details have improved greatly, but the basic concepts are very similar. 

 Pretty stinkin' cool stuff all the way around. Just goes to show that you never know what you don't know! Keep this in mind the next time you're at a sweet aviation museum.  Dig a little deeper into the displays cuz you just don't know what cool tidbit is just waiting for you to discover : )
