fireflybob,
I used to play that one... and I pretty much always won... especially with early students. Until I flew this 12 year old kid on a trial lesson... little bugger must have had a bionic eye, as he thrashed me!
Hmm Always difficult getting your students eyes out of the cockpit ... but they need too. I introduce it right from day one, and teach a 'search scan' with S+L.
