Are you suggesting we fly onwards for hours with only one conscious pilot?
For those rotary pilots who fly single crew, at night, into unsurveyed sites with sick patients in the back, this could be an interesting debate
Sipping my G and T in the back I would rather the FO flew into an airport he was familiar with, especially if relatively inexperienced. The risk of a second incapacitation is statistically tiny over a matter of hours.
