Loosbroek, Netherlands on 23 September 1923 while competing in the Gordon Bennett Cup. Olmsted remained in the race despite threatening weather which caused some competitors to drop out. Lightning struck the S-6 over Nistelrode, the Netherlands, killing Olmsted. Beginning on 11 August 1948, the 147th Flight Service Squadron of the Military Air Transport Service (MATS) began operations of the Olmsted Flight Service Center. During the 1948–1949 Berlin Airlift, the U.S. Supply Depot at Olmsted AFB provided emergency support supplies for the airlift operations. In 1958, Olmsted was designated as prime support depot for the T-38 Talon advanced jet trainer then under development and the L-27, later designated the U-3 Blue Canoe, support aircraft. Olmsted AFB and the Middletown Air Depot's last assignment was with Air Force Logistics Command (AFLC), and the base and depot were closed on 30 June 1969. Closure of Olmsted AFB Initially turned over to Pennsylvania Air National Guard after active-duty closure, much of the former Olmsted AFB flight line area was redeveloped into the Harrisburg International Airport under the ownership of the Commonwealth of Pennsylvania. In 1998, the Commonwealth of Pennsylvania transferred ownership of the airport to the Susquehanna Area Regional Airport Authority (SARAA). In addition, in 1966, much of the former Air Force property was converted into The Pennsylvania State University—The Capital College, otherwise known as the Harrisburg Campus. This campus was originally chartered as a graduate and upper division school.
