sycamore has it. Well done and to Mr Button for so nearly getting it....
X1B had a slightly different wing and 300 temperature sensors......
"The X-1B completed a total of 27 flights. A notable achievement was the installation of a system of small reaction rockets used for directional control, making the X-1B the first aircraft to fly with this sophisticated control system, later used in the X-15. The X-1B is now at the National Museum of the United States Air Force, Wright-Patterson Air Force Base at Dayton, Ohio."
Open House it is then.
