Thank you very much, Mr. Chair.
I appreciate your frankness and I agree it is a difficult issue. I think the answers that you're providing us are forthright, and for my part, I appreciate that. I think it helps put this whole issue into perspective, as difficult as it is.
Can you explain for me as a layman the difference between the service that's provided with an air traffic controller or the flight service station? Is there a difference as far as safety issues are concerned?
