I used to know 2 almost identical brothers - one in the forces - the other a civvy.
Both glider pilots,the serving brother arranged a fast jet flight for himself - and his brother came to visit the airfield on the same day - well who would have known the difference
? I would have struggled to tell them apart.
If something can be done we can all rest assured that it
has been done.
Slightly more difficult these days of course !Most things are more difficult.
