The first Boeing Business Jet (BBJ) takes off from Boeing Field on its initial flight with winglets. Although this is the first BBJ to be flown with winglets, Boeing used a 737-800 as a testbed for BBJ winglets last summer. Once the winglets are certified, they will be offered as a post-delivery installation feature on all BBJs. The winglets are being tested as a possible range-performance enhancement for the BBJ. The BBJ is a derivative of the Next-Generation 737-700, combining the -700 fuselage with the strengthened wings and landing gear of the larger and heavier 737-800.
