Col Glenn's flight was the second manned o … Col Glenn's flight was the second manned orbital spaceflight. The first was USSR Yuri Gargarin's orbital spaceflight. However, Glenn's space flight was set apart by the electrical and electronic systems invented by the MAC engineers, some being members of IRE and then subsequently IEEE. Its systems epitomize the field of interest of the IEEE Aerospace and Electronics Systems Society. Project Mercury's electronics included Navigation and control instruments; auto pilot; rate stabilization and control, manual proportional control system and Fly-By-Wire (FBW)manual-electrical system. The FBW manual-electrical systems proved critical to Friendship 7's mission success because a yaw attitude control jet apparently clogged at the end of the first orbit, forcing astronaut Glenn to abandon the automatic control system for the manual-electrical fly-by-wire system.

When the request for proposals was issued … When the request for proposals was issued by NASA, there had not been a manned spaceflight by the United States. Amazingly, James S. McDonnell, founder of the McDonnell Aircraft Company, dedicated resources and personnel to design a spacecraft capable of putting humans into space and returning them safely to earth at least two years before the signing of the Project Mercury contract.
Because space flight was different than conventional air flight electrical systems had new challenges. The electrical and electronics systems had to be able to operate in a new environment including but not limited to the vacuum of space, the weightlessness of orbital flight, and the rigors of launch and recovery. MAC electrical and electronics engineers took extra precautions because the spacecraft had to be ecautions because the spacecraft had to be

The Prologue room is open to the public du … The Prologue room is open to the public during the summer months and is visited by more than 5,000 non-Boeing people every year. In addition, the Prologue Room is used by The Boeing Company to explain the vast history of the company to domestic and foreign dignitaries. In addition, middle school students are given tours of the Prologue Room. They learn the mechanics of flight and they are encouraged to consider careers in math, science, and engineering. There is a visitor's parking lot next to Bldg 100 where the public may park and walk to the site of the milestone plaque. The Prologue is a secure area and Boeing provides daily security patrols of the area. The Prologue Room (site of Mercury Capsule MA-6 ) is inside the secure area of Bldg 100 -6 ) is inside the secure area of Bldg 100

The milestone plaque will be mounted at or … The milestone plaque will be mounted at or near the entrance of the James S. McDonnell Prologue Room: An Air and Space History Exhibit. The Prologue Room is located in The Boeing Company Building 100, headquarters for Boeing's Integrated Defense Systems business. This will provide public access to view the plaque. Inside the Prologue Room, there is an exact replica (mock-up engineering design fixture) of the Mercury Spacecraft MA-6 that Col. John Glenn piloted thru 3 earth orbits. The Mercury Spacecraft were designed, developed, and tested in nearby buildings less than 200 yards from where the plaque will reside. 0 yards from where the plaque will reside.
