NamibFox,
You're quite right, it would be great to know if we could land straight-ahead; however, like most twin-engined aeroplanes, a failure of one engine will most likely mean that we'll be committed to an unscheduled landing into a suitable vacant space within the countryside... that's a fact! Unless of course that you're flying for fun and that you're not carrying an appreciable payload; otherwise, we might fly the curvature of the earth and find a suitable route back to where we defied the original effects of gravity!
Ho-hum,
TCF
