In 1942, U.S. war policy placed first priority with the war in Europe. VIII Fighter Command Special Orders 46, dated 25 June 1942, deployed 86 aircraft and pilots of the newly designated 1st Fighter Group to England as part of Operation Bolero, with the first aircraft departing on 27 June. Flights of P-38s were led by individual B-17s from the 97th Bomb Group navigating the route between Presque Isle, Maine, Labrador, Greenland and Iceland. En route the 27th Fighter Squadron was detached at "Indigo" airfield, Reykjavík, Iceland, for air defense duty in July and August. On 15 July 1942, six fighters from the 94th FS, "Tomcat Yellow" and "Tomcat Green", and their two B-17 escorts were forced by bad weather and low fuel to land on a glacier in Greenland. The crews were all recovered safely but the aircraft were abandoned.
