Very good point. Flying alone is begging for the worst case, should the worst happen. While we can't live our lives worrying about what might happen, all too often the unexpected does happen. Why tempt fate. Use the buddy system. My Uncle was trying to run an Ignition engine (a GHQ) back in the late 30's. The engine backfired, threw the prop which severed an artery in his arm. He would have bled to death, had his sister not gone to check on him. He survived. The GHQ did not.
