A few years ago I was at work, which happened to be near the local
airport. Listened to planes going over all day. Then one day I heard
the unmistakable sound of a Merlin go over. Hmm... that sounded like
TWO Merlins. What could that be - a Mosquito? I couldn't get outside
soon enough to see it, so had to stop by the airport after work.

Tuned out to be something even rarer - a Spanish-built postwar HE111 -
with two Merlins. I understand that the plane was specially fitted
out as an executive transport, and was in it's day the personal
airplane of Francisco Franco.
