An SR22 collided with a Cessna 152  midair, miraculously both pilots live to tell about it. Almost all mid-air collisions between planes lead to multiple fatalities, since almost all parts of an airplane are required to maintain lift. These guys were lucky - landing gear smashed the windshield of the other plane. Landing gear and windshield happen to be 2 components not required for flight.        I just read some safety articles on midair collisions. Some of this is not so obvious. Worth sharing.     Over 50% of collisions happen in:   - sunny, vfr condiions (when you feel most comfortable)   - below 5000', near airport   - fast aircraft overtaking slow (if you're climbing at 73mph and he's flying at 300mph, you will only have a few minutes from moment of coming into your field of view, to him overtaking you)   - fast aircraft collides with slow from behind (0-15 degrees): how often are you scanning BEHIND you while flying?   - blossom effect: super counter-intuitive. an a...
