I remember… thinking that it was a Planet Satellite of the jet age, ie great vision and design, but possibly no market.

Great looking aircraft in flight, some pics and videos of it here courtesy of Machdiamonds.com, http://www.google.co.uk/imgres?imgurl=http://machdiamonds.com/leopard1.jpg&imgrefurl=http://machdiamonds.com/leopard.html&usg=__tCH83ZDZU6VVxi3bFnTNIVuD0ck=&h=360&w=732&sz=104&hl=en&start=1&zoom=1&um=1&itbs=1&tbnid=0d7_3NcK8skKwM:&tbnh=69&tbnw=141&prev=/search%3Fq%3Dcmc%2Bleopard%26um%3D1%26hl%3Den%26sa%3DN%26rlz%3D1T4ACAW_enGB337GB337%26tbm%3Disch&ei=XjE8TuKkMo7u-gaBv8C_Ag

At least the Leopard flew properly. The Satellite looked the business, but its two hop-flights both ended with a damaged aircraft and the CAA of its day declared a complete redesign was needed.
