This 2006 Airbus EC145 (BK 117C-2) N145SU of Stanford Life Flight is based on the roof of the Stanford Medical Center in Palo Alto, CA. It is one of three EC145s operated by Air Methods in California (i.e. Fresno and Children's Health of Orange County). Stanford's first helicopter was an Alouette III, N607RM, operated by Rocky Mountain Helicopters in May-August 1984, followed by a TwinStar N57898 (Aug 1984 to Sep 1986), a BK 117 (1986-2007) and a EC145 (2007-present). N145SU will be replace in Spring 2024 by a new Airbus H145 (117D-3) N1984S, msn 21114. Seen departing after refuelling at PAO.

Later fitted with a turret.

Former VH-UUI became N240G in May 1966, but in this photo it does not appear to be carrying its new registration yet. This General Aircraft Company Genairco Cabin biplane was first registered in Australia as VH-UOH on 2 June 1930, and reregistered as VH-UUI on 24 Sep 1936. In the late 1980s it was acquired by Kermit Weeks. Note the landing gear struts, inboard top wing struts, window and tail shapes.

Built in 1938 by the Sterling Edwards Co. of San Francisco, and powered by two 50hp Continental engines. Only one built.
