I love this kind of pics…if only we had them during the principles of flight lessons at high school: do you see that little wool thread attached to the sighting device on the left wingtip? That thing shows the relative wind, the airplane flying direction and the angle of attack or Alpha…just from a little tiny string. 📸 thanks philipplatzer #highalpha #cobra #angleofattack #aerodynamics #gravity #photography #airpower24
