Forum 77
Virtual | May 10-14, 2021
The Vertical Flight Society's virtual 77th Annual Forum & Technology Display, held online May 10-14, 2021, was a huge success! Thanks to all our authors, exhibitor and volunteers who made it such a great event. We had a record of 1,465 registrants!
Nearly 230 technical papers were presented, as well as insights and panel discussions by dozens of key decision makers in industry, the US Army, US Navy, US Marine Corps, US Air Force, NATO, NASA, FAA, EASA and other government agencies and research institutions, looking at everything from advanced rotorcraft to advanced air mobility.
