Thanks! I was thrilled we were able to pull it off...we were getting low on gas, and only had one run to do it in. The spacing between the birds ended up being about perfect. I was on quite a high after getting the capture. i never attempted one like this before.
(On a sidenote, this is an Apache, which looks quite similar to the Blackhawk if you aren't dealing with helos on a daily basis!)
I realized that right after I posted. DOH!
Thanks for the back story.
