Droopystop - I agree.
However, the kind of commercial operation which you may be half thinking of does this all the time... scud running at 400ft all the way across the Channel
Of course the pilot is the cream of the CAA cream, a class 1 medical every 6 months, etc. and no autopilot because fitting one would cost a fortune and real pilots don't need one
I am not suprised that, without pressurisation etc, these flights operate only over the water and not from say the south east to N Wales. Operating over any terrain, their despatch % would be pretty poor.
