Two Balloons colliding in Turkey?
Having just read that 2 hot air balloons collided in a fatal accident yesterday a thought has just occured to me...
How can this happen? The 2 balloons were at the same altitude so not only sharing the same airspeed, (zero), but also the same groundspeed.
Or perhaps the balloon that was hit was in the lee of the other but then the collision would be very gentle?
Any thoughts?
