Omni Air plane number N234AX, flight number CMB501 on contract to the US military, travelled a very unusual flight sequence on Sunday May 9th. It took off from Hill Air base which is a major US Air Force base in Ogden, Utah and flew directly to Shannon Airport. It then went on to Charles de Gaul CDG, Paris, then to Mont-de-Marsan Airbase, also in France.
Mont-de-Marsan is a secretive test facility for French cutting edge aircraft and related weapons systems. Wikipedia describes it as home to two squadrons of Dassault Rafale, the most advanced French fighter aircraft. The base includes Centre d'Essais des Matériels Aéronautiques - CEMA (the French air force military experimentation and trials organisation), an air defense radar command reporting centre, and an air defence control training site.
From there, N234AX headed north and then took an unusual turn rather than land at Charles de Gaulle, heading as if towards Ramstein. It made another turn heading south east again.
