If you ever have the chance to view the B-36 on display at the Aviation Heritage Museum in Fort Worth, Texas my initials are carved on the lower #3 inboard engine nacelle. I was on the pre-flight maintenance crew when that aircraft (serial no. 52-2827A) was being readied for its final flight from Biggs AFB in El Paso to Carswell AFB in Fort Worth on 12 February 1959 for permanent display at Amon-Carter Field. This was the last B-36 built by Convair. Click Restoration for the story of preserving this aircraft of the 1950s. I was also on the pre-flight maintenance of the very last B-36 to fly (serial no. 52-2220) which left Biggs AFB for Davis-Monthan AFB in Arizona in March, 1959, and then to Wright-Patterson AFB in Ohio on April 30, 1959 for permanent display in the Air Force Museum.
