Boeing completes first 787 GEnx engine runs

The first General Electric GEnx engines on a Boeing 787 Dreamliner came to life Monday with initial engine starts. Customers can choose between the GEnx engines and the Rolls-Royce Trent 1000 engines to power their 787s. Following engine testing, ZA005, the fifth 787 to be built, will undergo a series of ground tests similar to those conducted on the first 787s to ensure that it is ready for first flight later this quarter.
