I agree with what has been said above, but I have to chuckle when guys talk about 'avoiding collisions'. I have been flying about 17 years and have had 4 midair collisions. I seem to get one about every 4 years! [:@]

And on every one there were only 2 planes in the air! [:'(][:@]
It has been my experience that you never see it coming. I'm just tooling along when suddenly, WHAPP!! And little pieces flutter to the ground (and usually one big piece with a screaming engine arcing in like an artillery shell!). It's like what army men in the movies say; "You never hear the one that gets ya!".
Oh well. It happens!
