The KC-46 Pegasus tankers have appeared in the blog before but only on the ground.  That post can be found here.  I have finally seen them flying.  A couple of them were airborne on test flights from BFI and, while they had taken off quite far apart, they ended up returning quite close together so I was able to get shots of them both.  They don’t look terribly dissimilar which is what you would expect.  They are fully fitted out with the boom and one of them has the pods so this is what a service aircraft should look like when the Air Force squadrons start to get their hands on them.
