After more than 2 years of delays, Boeing’s new 787 jetliner finally took to the skies today. Flying for four hours, a 2 member crew will be doing basic tests and system checks to the jetliner. Around 25,000 people stood out in the cold and damp weather in Seattle to watch the historic lift off.

The testing doesn’t stop today. According to reports, over the next nine months a total of six 787s will be tested in conditions that are “well beyond those found in normal airline service.”

·         This take off has been delayed 5 times over the last 2 years
