• Amazing Boeing 787-9 Dreamliner video shows impressive takeoff and turns
• Flight was a rehearsal for Dreamliner performance at next week's Paris Air Show
• Pilot: "It looks like the takeoff is at a near vertical 90 degree angle — trust me it's not."

CNN's team at the Paris Air Show will be hosting a live Twitter chat with some of the biggest names in aviation. On June 15, at 11 a.m. ET [15:00 GMT,] CNN's resident aviation geek Thom Patterson will be discussing the future of flight with Solar Impulse pilot Bertrand Piccard; Chris Daniels, Director of Hybrid Air Vehicles; Brett Snyder, aka The Cranky Flier and Tim Robinson, Editor in Chief of Aerospace magazine.

(CNN)There's a famous quote: "If you did it, it ain't braggin'."

Boeing did it -- in front of a camera. An eyepopping rehearsal video Boeing released Thursday shows off its newest version of the Dreamliner aircraft — the 787-9 — performing some impressive and beautiful banks and ascents.

The takeoff alone will get your attention.

So maybe it's not bragging, but the flight certainly qualifies as world-class swagger for the Dreamliner, which is scheduled for a performance next week at the Paris Air Show. Watch these breathtaking "technical maneuvers" — as Boeing calls them — while the Vietnam Airlines plane soars over Moses Lake, Washington.
