I attended a talk at the Air Force Museum last month. One of the speakers was Leo Thornsness, a weasel driver who was awarded the Congressional Medal of Honor. He stated that one of the great advantages that the F-105 had was that it could go 800 knots on the deck and outrun any other airplane. That sounds like the afterburner was on. Also, multi-zone A/B's did not come into being until the TF-30 was developed. The J-75's A/B was either on or off, no intermediate power settings. The TF-30 had 5 settings or "Zones" as they were called in the business, each with its own spray ring. Going from military power through each zone until "Zone 5" was reached at night was a real gas. It was one of the few things that I did, that I thought would impress anyone; the sound, the sight!!
