Hi Rob, I agree about the friction part. Friction is most likley to reveal itself on the ground IMO. It is not something that the AF or USN would see or have to deal with like the Army would. From their world friction is almost none exsistant... fly a plane..drop bomb....go home...check if you hit it. Meanwhile the army sees that there is a ton of rubble blocking a road so a food shipment can't get through or an ambulance or whatever. The Army has to deal with that right now. "The Remore Control Services" just kind of wonder what the problem is. The final effect is best understood from a "Ground Assessment" before you start the cycle over again. Again just my opinion.
