Some years ago now we had gone in the motorhome to Abbottsford Airshow, we got the whole weekend package which meant Friday to Monday. They had two B-1's there, one on static display and the other doing the flying demos. On the Monday morning they took off together and disappeared into the fairly low cloud, but a short time later they came ripping back in from the sea at low level, both had large cones of condensation clouds circling the airframes. Quite the sight to see ----
