The first Boeing 787-10, BOE1, completed its first flight from the Boeing facility in North Charleston, South Carolina, on March 31. The flight took off at 9:30 a.m. local time and landed at 2:35 p.m., just over five hours later.
Boeing test & evaluation captains Tim Berg and Mike Bryan piloted the aircraft. The flight reached 20,000 ft. at a speed of 383 kts., or 441 mph.
In a post-flight press conference Berg and Bryan said they “enjoyed the whole day. “Berg said, “We had a great plan, we had a great team and we had a great jet. We did exactly what we wanted to and it performed exactly like we thought it would. And that’s about as perfect as it gets for a test pilot.”
The weather in Charleston had been dubious through the morning, with heavy cloud cover and spits of rain. At about 9 a.m., the clouds parted and the sun appeared, creating an ideal window for the aircraft’s takeoff.
At about 9:20 a.m., the -10 appeared before thousands of Boeing employees and guests and made a slow taxi/photo shoot before rounding the runway start point and commencing with its takeoff into a now clear and blue sky.
Boeing rolled out the first 787-10 from its plant in North Charleston, the exclusive site for 787-10 final assembly, in a Feb. 17 ceremony attended by US President Donald Trump.
