It isn't the concept of a UAV tanker I find amusing, it's the land first pass, every time, even in bad weather that is laughable.
Well, as long as the conditions are inside the parameters for the system, sure. A system like TALS will even exceed it's own advertised capabilities well beyond what anyone would expect. It is a true honey badger.
The DGPS system for the RQ-21 is actually really good as well. It's the fact that the airplane only weighs 135 lbs soaking wet that we have such wind and pitch/roll limits at the boat.
So sure, first time every time is a little alcohol induced hyperbole, but I'm willing to bet a lot of money that the machine will do it better and more consistently than a human.
