Flight testing 214ST with BH.
I had been assigned the flight testing responsibilities for the third (of three) 214ST prototype aircraft. On one flight in the South Arlington, Texas area, while gathering data on Bell's first indigenous SCAS / Altitude - Attitude - Retention - System, the pilot and I had discovered a slight error in the system. We were gathering data on the symptom with our eyes inside the cockpit, when I looked up to see a Cedar Hill Radio Tower guy-wire orange ball directly in front of us. I had time to say 'Holy Crap' and the pilot abruptly banked left and cleared the wire by ??? (an inch is as good as a mile). 30 some odd years ago and I remember it vividly. Otter
