Boeing puts a fifth 747-800 freighter into testing

Boeing (Chicago, Seattle, Wichita and Charleston) successfully conducted the first flight of the fifth 747-8 Freighter on Thursday (February 3). The airplane, coded as RC523, took off from Paine Field (PAE) in Everett, WA, for a 3-hour, 30-minute flight before returning to Paine Field.

The flight included a standard 2-hour, 30-minute “B1” flight profile that Boeing conducts on all production airplanes prior to delivery, plus an hour of engineering testing woven into the profile.

This is the fifth 747-8 Freighter being used in the flight-test program. Each airplane is used for a specific set of tests, with this airplane focusing on functionality and reliability testing.

The airplane will remain based at Paine Field throughout its test plan.
