There was a midair in the pattern of two Riddle 172s 25 years ago, one a dual crew, the other a solo student on his second solo, I believe. Dual crew misidentified company traffic while on an opposite downwind to base. Collided with the solo student. Solo student's main landing gear strut and wheel went through then front windscreen of the dual crew and the tire smacked the CFI in the head. The two planes were stuck together for a moment with their wings smacking into one another before separating. Dual crew smacked the ground short of the runway. Solo student landed his plane. No fatalities.
Dual plane a write-off, solo plane heavily damaged but repaired.
