Following his graduation and commissioning, Jack was stationed in Selma, Alabama, where he earned his pilot wings in 1962.

Jack resigned from the USAF in 1966, after having served as an instructor pilot and accumulating 2,000 hours of flying time. He was hired as a Service Foreman with the C&P Telephone Company in Baltimore. In the 1980s, while a C&P District Manager, he planned and supervised the installation and maintenance of telephone equipment in many of the city’s large office buildings, including the USF&G and IBM buildings, City Hall, and the Maryland State Office complex.

After 26 years in various technical and management jobs with C&P (and later, Bell Atlantic), Jack retired to pursue his interests in golf, family, and the Exchange Club of Highlandtown.
