Cobden Air Services
Cobden Air Services have more than forty years of experience in aviation. As soon as he was able to apply for an aircraft pilot's license Ken Cobden learned to fly in a Tiger Moth and commenced his love of aviation.
Two of his sons followed in his footsteps and fly with airlines. His first aircraft purchased in 1961 was an Auster. Since then Ken has owned about 28 aircraft, which included a propjet. He has also flown numerous other aircraft.
Looks like they operate an Aerostar and a Chieftain.
