Eagle Attack RC Glider.

Eagle is a very intelligent, smart and brave creature.
My brother flying his Hobbyking phoenix 2000 glider in good thermal When suddenly one, then two and finally 3 eagles appeared seemingly out of nowhere. At least two strike or contact was made with the glider, which was equipped with the an on-board camera. Unfortunately the on-board camera stopped shortly before the eagles appeared but still good footages from ground. Wingspan if the eagle 🦅 was similar to the glider: 2 meter or 6+ feet.The glider later landed not quite well
