And it was VERY fast. Look up the records they set and then
do some algebra. KC 135 tankers can do about 500 knots and
the SR 71 refueled twice on the record trip California to
London. Just figure out the maximum speed of the SR if it
spent a total of 30 minutes in the refueling process on a 2
hours flight...dash speed of 6,000 maybe.
