Here is a view I've had many times, a B-52 getting refueled from a tanker at probably thirty thousand feet or so.  This is very routine now but at first it wasn't and in the days in the 1960's when I was a flight surgeon and required to be on both the tankers and the bombers this was a never ending fascination.  Here is the view from the tanker and what I talk about in the prologue of Full Moon Saturday Night.  Count the engines on the bomber. Eight of them!
