Hi Gertrude!
You said:
" Ah, well, Vancouver Island is certainly different to south-east England ..."
Of course it is, more mountains for one thing..
However my comments were aimed at choosing a safe landing area for an engine out landing.
Please read my comments again and maybe point out where I was wrong?
Have another look at the airplane in the picture that landed in a field with a standing crop, then consider the odds of flipping upside down on a road.
By the way I am well aware of the road system in England, however there are roads that are landable...
Anyhow read what I posted and I believe that I am correct in my comparison between the chances of a safe landing on a suitable road versus a field with a standing crop.
