Long before Eclipse, Cirrus or even Lear Jet, the Morane-Saulnier MS-760 brought jet performance to personal aircraft. In production from 1959 to 1966, the four-place twinjet was powered by a pair of Marbore straight-pipe turbojets and sold reasonably well for its time. Now, a new company plans to revive the design, known as the Paris Jet, providing update and refurbishment services to existing MS-760s and possibly resuming production with updated engines. Steven Fox, president of MS760 Corp., was at the NBAA convention last week reporting he had assembled 20 remaining MS-760s and a stock of spare parts and engines. He said he could deliver seven of the little jets within as little as 30 days - and as many as nine more next year at a selling price of $450,000. MS760 Corp. is also considering re-engining the Paris Jet as a single, using either a Pratt & Whitney Canada JT15, a P&WC 600-series turbofan or a Williams International FJ44.
