I agree,
Now about reflecting off of odd shaped things. A buddy an myself used to in the late 70's have fun on 2 meters just playing around. we were too far apart for direct communication, I was in the northwest suburbs of Chicago, he was down in central indiana.
We would point our 4 ele beams at eachother and run like a meteor scatter transmission sequesnce. and would make a qso. it was flaky and wide variations in signal strength. But what did we use?
It was all the Jets coming in to land at Ohare! between us was the main route for all the jets to com in on. The route killed TV all the time by making signals in phase and then out then in then out, so we thought if it's strong enough reflection to cancel out a direct megawayy signal, hmmm. so we tried and it worked and worked faily well. each "Opening" lasted between 10 and 15 seconds. and would go most times from s zero to peg the meter.
was fun and thats an odd shaped reflector. that for me was ohhh 60 miles away, and for him close to 100 miles.

Hi Joe, WB9SBD
I agree that the QSO was possible because It was the reflection of all the Jets coming in to land at Ohare! between you and your ham friend it was the main route for all the jets to com in on.
For the above reason I have sent to you a zipped file of a very interesting article on this matter titled "Aircraft Scatter" written by Kent Britain, WA5VJB.
If someone is isterested on it drop me a request off line.
