From Tom’s article @ https://tomhuttonmd.com/category/f-105-thunderchief/
‘On a dive bomb run at some long forgotten place, I marveled at the countless projectiles heading my way. There were bright colored tracers and those that were less visible shades of gray. The anti-aircraft guns usually focused on the plane presenting the most immediate threat and all of them seemed to be firing directly at me. It looked as if each round was destined to come through the center of the windshield. That none of them had hit me yet seemed impossible. At a speed close to 600 knots, I glanced out the side of the cockpit and it seemed as though tracers were actually arcing up and over my right wing, following the airflow around it. I dismissed this as an optical illusion and concentrated on the delivery of the bomb load. The ripple of the six thousand pounds leaving the aircraft meant that it was time for afterburner and lots of back stick. Vision grew narrow then dim as the G load increased, in spite of the functioning of the G suit and the tightening of body muscles. Acceleration to maximum speed and heading for relative safety away from the target followed. This same drama was to be repeated thousands of times by hundreds of pilots over the next seven years.”
