I'm glad someone else has mentioned other aircraft, but the nosewheel configured are less hazardlous than tailwheels. I'm thinking of C180/185 series with flat battery. Long 2 bladed prop leaning back. As the prop reaches 12:00-6:00 position or so the prop swinger now has to push UP. Doing so forces him to step closer to the danger area. As pretty much usually happens, it tends not to catch on the safer downpull. Always the much more hazardous pushup. A real trap for the unwary.
