An extraordinary privately owned airfield in Maryland has been gifted to the RAF by the late Bob Armstrong, out of the Armstrong family’s passion for aviation. High Rock Airfield lies within a sweeping bend of the North Branch of the Potomac River and brings another eastern US destination into the RAF’s Expanding the Map initiative. A true gem of the East, it offers a real backcountry experience just 85 nm northwest from where the Arlington Memorial Bridge crosses the Potomac in bustling Washington, DC. “We are humbled to have become the stewards of this special place, and will honor the Armstrong family’s legacy by creating a welcoming place to enjoy the fellowship of backcountry aviation,” said RAF President Bill McGlynn. Bob and his father, Lt. Col. Harold Armstrong, were indeed passionate about aviation and based their multiple rare aircraft here. Bob was a lifetime member of the EAA, the Aeronca Club, AOPA, the QB Club, the OX-5 Organization, the Cumberland Soaring Group, the Soaring Society of America, and the Vintage Sailplane Association. He and Harold collected vintage aircraft and gathered numerous awards for their pristine workmanship. One Aeronca Champ restoration won the highest “Lindy Award” honors at EAA’s AirVenture competition in Oshkosh.
