Remarks: A very rare glider. At the moment there are only two flyable SB-7 in germany. This one is based at Nordholz-Spieka (EDXN) and was private licence-built.
This flight was a testflight and the mission is to improve the wing. On the right wing you can see a modified part and the red fluid shows the aerodynamic-result during slowflight-conditions!
Remarks:Speedbird 142 holding short right in front of us, for nearly 15 minutes, as she begins her journey back home to London Heathrow International Airport. I was on my 50mm lens, and this is all I could fit in my lens. This was a bad start for her flight as she was pushed back from gate and was made to wait for 10-15 mins, then this delay in front of us, and again a delay of 10-15 minutes on Charlie Whiskey 1. Definitely an unhappy crew and passengers on this flight.
