Bruno Vassel's video: Wind Shear on Short Final - Glider Instantly Loses 100 Feet

This is the best example of experiencing wind shear coming in to land in my 25+ years of flying both gliders and airplanes. It was much more dramatic than it first looks in the video. It felt like the bottom just fell out from under the wings of the aircraft and luckily my instinct and training told me to push forward on the stick and not back to try to salvage the airspeed. Notice how losing that 100 feet instantly still kept the same airspeed. In a normal situation, 100 feet of altitude would equal an additional 20 knots of airspeed. The winds were blowing down the runway at about 20-25 knots at altitude. Once I got closer to the ground the wind instantly vanished leaving me close to stall speed had I not pushed the nose down. Its pretty difficult to do when the ground is so close, but it worked. This is an ASW27B high performance glider / sailplane and the airport was in Hobbs, New Mexico. Thanks for your comments and for watching! Bruno - B4
