Military service

Manufactured by Hawker Aircraft Limited, Kingston-upon-Thames, in 1958-1959 as s/n XE-49,[N 2] N58MX made it's first flight in the hands of Don Lucey at Dunsfold on 3 July 1959. Delivered to Dübendorf on 02 September, the aircraft was assigned to squadron service on 9 September[1] as J-4061.[2]

In 1964 J-4061 was modified to carry AIM-9 Sidewinder missiles. Before it's retirement on 2 December 1994 at Emmen AFB, the aircraft had also been equipped to carry the Maverick AGM-65B optically-guided missile system. During it's career, J-4061 served with SAF Squadrons 9,10,13,15,18,19 and 20, making 1708 landings over 2803.47 flying hours.[1]

Civilian use

On 3 May 1995, J-4061 was ferried by Ruedi Erni from Emmen to Altenrhein, where it was modified & prepared for ferry to USA. Flown from Altenrhein to Southend (UK) via Basel on 11 September 1995, J-4061 experienced a tailstrike on landing, which was repaired by Jet Heritage, Bournemouth (UK). Ferried to USA during 13-15 April 1996 by Brian Grant, J-4061 went to the Mid Atlantic Air Museum, Carl A Spaatz Airfield, Reading, Pennsylvania, USA,[1]

A certificate of airworthiness for J-4061, now registered as N58MX, was issued on 4 June 1998. On 2 April 2003, N58MX passed to Robert E Guilford, Los Angeles, CA,[3] who operated the aircraft from Van Nuys Airport, California.[1]

Still wearing Swiss Air Force camouflage when it appeared at the Miramar Marine Corps Air Station Airshow on October 18, 2003,[4] N58MX had, by March 2004, been repainted in the colour scheme of the 'Blue Diamonds' aerobatics team of 92 Squadron RAF.[2]

On 16 July 2006, at 1628 Pacific daylight time, N58MX was destroyed after colliding with terrain while maneuvering during the Oregon International Air Show.[N 3] Robert Guilford, the registered owner and operator of the airplane, was fatally injured. The subsequent investigation concluded that the crash was caused by loss of aircraft control for undetermined reasons during the takeoff sequence.[5]


  1. The loss of N58MX occurred shortly after filming of the episode was completed.
  2. Forward Fuselage no 41H/698746 and Centre Fuselage no 41H/697428[1]
  3. Event coordinators reported that the pilot planned to make 3 non-aerobatic low passes over the runway after departing from runway 30. Subsequent to completing the maneuvers, the pilot intended to continue the flight to his home airport in Van Nuys, California. At the time of the accident, N59MX carried an experimental category airworthiness certificate, issued on April 15, 2003, by the Boise, Idaho, Flight Standards District Office (FSDO).
