Each year at the Hiller Aviation Museum at San Carlos Airport holds it’s annual Vertical Challenge Airshow. The two day event started on Friday with the arrival of military helicopters from southern California. Participants included a US Navy MH-60S Seahawk helicopter from HSC-3 “Merlins” based in North Island Naval Air Station, San Diego, two US Marine Corp CH-53E Super Stallion helicopters from HMH-462 “Heavy Haulers” based at Miramar Air Station, San Diego, and a US Marine Corp CH-46 Sea Knight from HMMT-146 “Knight Riders” which flew in from Camp Pendleton, CA. That night Hiller put on the only twilight airshow in the country featuring famed helicopter act, Otto the Clown Helicopter, a S.A.R. Demo by the California Highway Patrol with their A-Star helicopter, a helicopter lesson and concluded with the unique Go Fast Jet Pack.
Saturday along with the heavy military hardware, the civilian presence was added to with appearances from Stanford Life Flight medical helicopter, USCG HH-65C Dolphin, a Vietnam era Huey, several Bell 47’s, and other unique helicopters.
