Orang-orang mengembangkan pesawat terlebih dahulu dan kemudian menjaga keselamatan penerbangan. Jika orang-orang fokus pada keselamatan dulu, tidak ada yang akan pernah membangun pesawat. Asli: People developed planes first and then took care of flight safety. If people were focused on safety first, no one would ever have built a plane.
