Have either of you actually flown in Africa, where people taking a short cut across an active airfield is not unknown?
We had an ''official bird scarer'' in a hi-viz jacket run across the runway at Addis a few months back. We were somehwere near V1 when it occured and we did not see him due the curve in the runway until it was too late.
5 seconds earlier and we would have shattered him with the nose gear.
Quite some sight..!
