Lindsay J. Lina, 97, died Wednesday, May 13, 2015 at Lighthouse Pointe in Chesapeake, Virginia. Mr. Lina was a 1939 graduate in aeronautical engineering from Louisiana State University. He was employed shortly after graduation by NACA (now NASA) as a flight research engineer. His long career at NASA was interrupted only by his military service, when he served as an Army Air Force pilot during WWII. His work at NASA included contributions to the lunar landing program, development of anti-skid brakes for various aircraft, characteristics of high-speed flight, and pioneer work in the development of visual flight simulation for fighter aircraft. After his retirement, he enjoyed flying as a private pilot, and particularly delighted in playing golf with his many friends at the Woodlands Golf Course in Hampton. Left to cherish his memory is his wife of more than 75 years, Mary Moss Lina, formerly of Hampton. He also leaves four sons and their families: John and Angela Lina of Chesapeake, VA; Walter and Cathy Lina of Calabash, NC; Michael and Paula Lina of Portsmouth; and Bill and Jane Lina of Virginia Beach. He is also survived by 5 grandchildren and 3 great-grandchildren. A Mass of the Resurrection will be celebrated 9:30 AM Saturday, May 16, 2015 at Immaculate Conception Catholic Church by Rev. Sean Prince. Interment will follow at Parklawn Memorial Park. Services are by R. Hayden Smith Funeral Home in Hampton, 757-723-3191.
