I was flying with a friend of mine a few weeks ago and there is a little 'one horse' field close to me and my friend picked me up and and we made a flight on the return he was going to park the plane and come to my house. For some reason there was a DEA (Drug Enforcement Agency) helicopter there (prob getting fuel or something) .... as my friend leaves he spins the plane around and cliped the tail of the helicopter.... THANK GOD I WAS NOT in the PLANE! hahaha Very minor damage (both could still fly) BUT the SH*T it caused! WHEW! Out of EVERYTHING he could have clipped he picked a government helicopter! hahaha
