Way back in the early 50's, we lived near Bovingdon, so there were always different types of 'aeroplanes' going over.
One day (I was about 4 years old) I heard a 'plane, looked up and saw this aircraft with 6 propellors on the back of the wings. I ran indoors and told my elder brother (he would have been about 7 so would have known everything).
He hit me, telling me no such 'plane existed!
NB: I wouldn't think it landed at Bovingdon, but it was heading that way about 3 miles away.)
