This aircraft once took it's pilot to over 4500 MPH. It flew above Mach 6

When I used to live in Hemet, California, I was at one time a volunteer for the March Field Air Museum and part of the Adopt-an-Aircraft Program, I adopted the Museum's UH-1F Huey Helicopter s/n 63-13143, I didn't know it until later on, but I found out that this special UH-1F Huey was at one time one of the support aircraft for the X-15 Test Flight Program, it has recently been re-painted in camo colors by the the March Field Air Museum's Aircraft Restoration Manager Mr. Rudy Lerma and his Restoration Team, stop by the Museum sometime and take a look at it.

I am searching for NACA or USAF documents relating to the mid-1950s proposed (and quickly abandoned) orbital X-15B. The plan was to launch and orbit a beefed-up version of the X-15 on the back of a Navaho rocket. Any suggestions where to look?

It seems that X-15A-2 should have a ceiling of 314,750ft while X-15A should have the 354,200ft ceiling -- not the other way around. X-15 ship 3 was the only one to reach 354,200ft.

take a look at my website:

The X-15 remains a constant reminder to me on how the U.S. 'kicked butt' to build and fly the fastest aircraft in the world during that time. It was a cornerstone to me knowing that, even though we lived under a constant nuclear threat, we had provisions that may not have been defendable, therefor, patterning a significant theory to uphold our (U.S.) way of life. What can I say? I wish I could've strapped into one of those...or maybe a[n] X-14...do you recall that one?

I have a web page devoted to the X-15 at:


There are lots of links to technical papers, as well as aero data and vehicle characteristics. The X-15 is my test case for the flight dynamics model I am writing (JSBSim) for the open source flight simulator called FlightGear (www.flightgear.org).
