John E. Jenista was born on 19 September 1929 in Chicago, Illinois.  He graduated from Lyons Township HS in Brookfield at the age of 16 and then attended Lyons Township Junior College for two years. John started his Navy career in 1948 in the Flying Midshipmen Program and earned his commission as an Ensign.  He was first assigned as a pilot to Patrol Squadron Forty-Six flying PBM seaplanes during the Korean War.  He next took orders as an All-Weather flight instructor in Corpus Christi, Texas, where he met and married LTJG Patricia J. Flynn, US Navy Nurse Corps.  John earned his undergraduate degree in Mathematics and a Master’s degree in Aeronautical Engineering at the Naval Postgraduate School in Monterey CA. He served 20 years on active duty before retiring in 1968 as a Lieutenant Commander. The family moved to Wichita, Kansas where John was a program manager for Beech Aircraft Corporation. He was solely responsible for the conception, development, and sale of the T-34C turboprop aircraft.  This airplane became the Navy’s primary trainer for the next 30 years. John took every opportunity to fly Beech aircraft, and Mrs. Beech often personally requested him for her business travel. He became proficient piloting every airframe that Beech built. In 1980, John moved the family to Fort Worth, Texas where he became a project manager for General Dynamics Corporation. A lifelong and highly experienced aviator, he logged over 11,000 hours in numerous military aircraft including jets. In the civilian world, John was an active member of the Experimental Aircraft Association (EAA), a sailplane instructor, and a Quiet Birdman. He realized his dream of living on an airport and owning a V-tail Bonanza, which he proudly flew in multiple cross-country races and to visit family in distant states.
