[Scan-DC] Air Refuel Question

[Matt Carter]

Perhaps the folks who listen to the CAP over DC can shed some 
light on this one.  

Yesterday at about 6:30 PM while on Mass Ave near Rock Creek 
Park and looking South I saw what I'm assuming to be a refueling 
op.  There was a large plane with a small plane right on it's wing 
flying nice and slowly to the E/SE.  They were low eonugh for me to 
make out both planes (my guesstimate is 20k feet give or take) and 
couldn't have been outside the beltway.  There was also another 
fighter coming from the same general area as the other two planes.

I've never seen this before, and had always assumed that refueling 
happened off-station a bit, especially over densely populated areas 
(due to the inherent risks of having two planes witin feet of each 
other).  Did I see a refueling, or was I watching a fighter escort, or 
am I just crazy?

Thanks!!!

Matt
