The first USAAF unit to use the airfield was the 13th Photographic Squadron of Lockheed F-5 (P-38) Lightning photographic aircraft which moved in for training in March 1943 under the experienced RAF establishment.
This was the 13th Photographic Squadron.
 The need for more photographic reconnaissance of targets by the Eighth Air Force led to other American photo/recon squadrons being assigned to the station and on 7 July 1943, the 7th Photographic Group was established at Mount Farm, the group being transferred from Peterson AAF Colorado and absorbing the assets of the 13th photo squadron.

The group consisted of the following:
13th Photographic Squadron (red rudder)
14th Photographic Squadron (green rudder)
22nd Photographic Squadron (white rudder)
27th Photographic Squadron (blue rudder)
The group flew a combination of F-5 (P-38), P-51 and Spitfire XI photo/recon aircraft to obtain information about bombardment targets and damage inflicted by bombardment operations.
 The group also provided mapping service for air and ground units; observed and reported on enemy transportation, installations, and positions; and obtained data on weather conditions.

Ace RAF reconnaissance pilot Adrian Warburton, attached to the USAAF reconnaissance operations at Mount Farm, and under the command of Elliott Roosevelt, took off from here on April 12, 1944, in an F-5B Lightning for a reconnaissance flight to Schweinfurt, on which he was shot down and killed by flak.

Prior to June 1944, the group photographed airfields, cities, industrial establishments, and ports in France, the Low Countries, and Germany.
Following the Berlin raid in March 1944, Major Walter L Weitner flew the first Eighth Spitfire photo sortie to Berlin on 6 March and by 11 April the Group had chalked up its 1,000th sortie.

The 7th received a Distinguished Unit Citation for operations during the period, 31 May - 30 June 1944, when its coverage of bridges, marshalling yards, canals, highways, rivers, and other targets contributed much to the success of the Normandy campaign.

The group covered missile sites in France during July, and in August carried out photographic mapping missions for ground forces advancing across France.
Provided reconnaissance support for the airborne attack on the Netherlands in September and for the Battle of the Bulge, December 1944-January 1945.

The 7th used P-51's to escort its own reconnaissance planes during the last months of the war as the group supported the Allied drive across the Rhine and into Germany.
 Took part in the final bomb damage assessment following V-E Day.

The 7th Recon Group took over three million photographs during the course of its 4,251 sorties.
 It was transferred to RAF Chalgrove in March 1945, and was later inactivated at the 4th Strategic Air Depot (Hitcham) on 21 November 1945.

From here stars including Bob Hope, Dorothy Lamour and Glenn Miller took off to entertain the troops in Europe.
Miller performed for the US service personnel at the base in December 1944.
From there he went to RAF Twinwood, boarded a Noorduyn Norseman single-engined aircraft, took off for Paris - and was never seen again.
His plane is believed to have ditched in the Channel - although 20 years ago there was a belief he may have crash-landed in the dense Chilterns woodlands.
Searches found no trace of the aircraft.
