To help cover the costs of tuition and living expenses, he signed up for active reserve duty with the 434th Troop Carrier Wing at Bakalar AFB, Columbus, Indiana, as a flight engineer on Fairchild C-119s.

While at Boeing, Raisbeck and a team of engineers and flight crew designed and flight-tested an internally blown trailing edge flap system on the prototype 707, 367-80, known as the Dash 80.

The Dash 80 first flew in December 1963, and soon demonstrated flight at speeds as slow as 60 knots, at gross weights exceeding 150,000 lbs.

In 1969 Raisbeck left Boeing to work full-time at Robertson Aircraft, where he soon became chairman, CEO, president and chief engineer.

The Redhawk wing featured movable leading edge devices, Fowler flaps and spoilers for roll control.

He worked for one year for Allen E. Paulson at American Jet Industries in Los Angeles as vice president of technology.

Having problems with the wing redesign, Raisbeck became partners with Howard in February 1975, to enable him to complete the development of the Mark II system.

His vice-president, Joe Clark, arranged a deal with Morrison-Knudsen and got Raisbeck started on developing the Mark VI system of performance enhancements for the Beech Super King Air.

Clark would later go on to co-found Horizon Airlines and Aviation Partners Inc.[2] The Mark VI system included nacelle wing lockers,[8] dual aft body strakes,[9] exhaust stack fairings, engine inlet ram air recovery system, high-flotation landing gear doors[10] and enhanced performance inboard wing leading edge.

[2] Turning to airliners, in 1996 the Raisbeck Commercial Air Group completed recertification of the Boeing 727 to meet Stage 3 noise limits without weight and performance penalties.

Aerodynamic innovation provided Stage 3 noise compliance without costly engine modifications, saving their operators several million dollars on each installation.

Because of the design of enlarged bins, popular, 22-inch, upright bags carried by passengers could be stored crosswise, with the handle facing the door.

The doors included rapid decompression, emergency pilot egress and crash-crew cockpit ingress, bulletproof protection, cockpit-to-cabin visual identification and structural integrity.

The ZR LITE wing and flap system reduces cruise drag by almost 10 percent and increases the FAA-certified takeoff performance, allowing these airplanes to operate safely into and out of many previously unavailable airports.

[2][17] Work is currently underway at Raisbeck Engineering on developing an aft fuselage locker system for the Learjet 60 aircraft.

The Raisbecks were selected as the 2007 Seattle-King County First Citizens for their generous support of local arts, education and medical research organizations.
