Lt. Mingenbach's Statement

4 December 1953

S T A T E M E N T

Lt Moncla and I had been on five minute alert on Monday afternoon 23 November 1953. The fifteen minute crews came on at 1700, stayed until 1745 and then left for dinner. They returned about 1815, and were about to takeover 5 min from Moncla and I when the scramble horn blew once and Lt Moncla was airborne about 1820. My R.O. and I left the alert hangars for dinner at 1825, returned about 1900, and I called Naples requesting a C.A.P. mission. Permission was received immediately and we were airborne about 1915. I called Naples on channel 10 at 1918 and was told to vector 330 degrees, angels 20, assigned call of Avenger Black, informed that radio & radar contact had been lost with Avenger Red and to attempt contact with him on channel 10. Until I was told to return to home plate my R.O. made continuous attempt to contact with him on VHF channels I, 9, 10, 11, 1, and guard. During the climbout I encountered a broken ceiling at about 3000 feet, and subsequent layers of overcast to angels 20, where I requested an altitude change from GCI to angels 30. Permission granted I continued the climb and broke out above all clouds at angels 29. No icing encountered on climb. At about 1935, heading 330, altitude 25,000 my R.O. and I both believe we heard a short transmission from Avenger Red, recognizable as his voice, for about 5 seconds on channel 10. He seemed to be in the middle of a sentence when his transmission broke through, and therefore meaning was unintelligible. We called him back several times and received no reply. Shortly after this we were vectored 270, cruising at angels 30, and control was passed to Pillow.

My radio reception was very good, since I was clearly reading Naples vectoring Avenger Purple where I was 150 mi from home plate. Pillow vectored me over the area where contact had been lost by them with Avenger Red, and requested that I letdown in that area to investigate. Kinross weather had forecast moderate to heavy icing and snow showers for the local area, and since I was not sure that my anti icing system was operative, and did not have retractable engine screens, I hesitated to letdown into icing conditions that perhaps had given trouble to Avenger Red. Also snow showers combined with a low ceiling over the lake would have rendered effective search impossible in that area. I was informed that the request for me to letdown had come from Horsefly, and therefore Pillow nor Naples could do anything but have me orbit the area and continue to attempt radio contact with the lost aircraft. Finally, when Avenger Purple had come within 30 miles of my position, we were both told that Horsefly requested we return to home plate and land. A normal letdown at Kinross was accomplished under Naples control, light icing encountered between 17,000 and 6,000 feet, and I landed at 2055.
