"The G650 excelled at its top speed of Mach
0.925," O'Meara said. "Even at near the speed of sound, the
aircraft provides stable and precise handling characteristics.
It's very responsive to pilot input with fantastic maneuver
capabilities. Turns can be initiated and completed without
any onset of buffet."

At the conditions flown today, the entire operation was flawless.
The aircraft's capabilities and state-of-the-art technologies
make it very easy to fly and will enhance our customers' experience

offers the same cabin cross-section as the Bombardier Global
Express XRS, but longer ranges at higher speeds.
Design requirements included a bigger, quieter,
more comfortable and reliable cabin; a range of 7,000nm at
M0.85 and 5,000nm at M0.90; and a maximum take-off weight
no greater than 45,360kg (100,000lb) for access to key airports
like New York’s Teterboro.
The G650 offers the longest range at the
fastest speed in its class. Powered by best-in-class Rolls-Royce
BR725 engines, the business jet will be capable of traveling
