Yep Cameraone I am aware of the windows along the side, I see VC10's every day, every hour in fact overhead and have flown in one before. What I really meant was is there any specific viewing window designed to see recipient aircraft at closer quarters as there are on , say KC135 (I appreciate that KC135 does not refuel from a drogue and you can get above the probe), other than looking out of my distorted perpex porthole.
