RC001, Boeing’s first 747-8 Intercontinental, is spending tonight and tomorrow conducting the first of three systems check-out simulations called gauntlets. The first, known as the factory gauntlet, will begin tonight inside the 40-22 building at the Everett factory which holds the 747-8 final assembly line. You may remember the factory gauntlet from the preparations for 787 first flight in 2009.
