Were Warburton's remains found recently near a Bavarian village in the plane's wreckage and given a burial service right there nearby? I read a few months ago about lone P-38 Lightning reconnaissance missions flown by a few RAF pilots.
So many missions were flown by one pilot, very far from homebase in planes with little or nothing in the way of defensive weapons, as are many missions these days. Many reconnaisance crews were also lost near or over the Soviet Union in the "Cold War".
