Somewhere I've read a quote from Boyd (probably; otherwise, one of the other members of the LWF Mafia) in a paper discussing energy maneuverability, in which it is stated that there had been no increase in fighter Ps (in fact, a decrease) since the F-104. The period of the report in question must have been the late '60s or early '70s. Walt BJ flew the hottest F-104, the A model retrofitted with the same J79-19 engine as in the Sparrow-armed F-104S, but without all the avionics associated with the RHM capability. As Walt can tell you, that bird was awesome. About the only fighter that was in the same ballpark in that era performance-wise was the Lightning, but that had a pretty poor weapon system for air combat (though better for interception than the F-104A or C). A now deceased friend of a friend flew virtually all models of the F-104, including the G (he flew the C in combat), and liked the G the least. IIRC (this is via my fading memory of what my friend said his friend had told him whilediscussing the a/c), he said that it was relatively heavy and the Cg was more forward (presumably owing to the more powerful radar and more complete avionics), and he also didn't care for the bigger tail. Now, please note that he was assessing it as a pure air superiority fighter, as opposed to the multi-role fighter (nuke and conventional strike/recon/limited all-weather interception/maritime strike) missions that the F-104G was required to perform, where all the extra weight of avionics (and airframe beef-up) was necessary. Oh, one correction to a point Ed made in a post; the 104 usually had its greatest Ps advantage fast and low, not fast and high. About the only time F-8s (any other US fighter of the period was a grape against a smartly-flown Zipper) could give them problems was at high altitude and low Mach, where the104's skimpy wing was very unhappy.

Not sure who to attribute that too, but it seems to be lurking in my old memories of a Top Gun lecture. R / John |

The past ten years, the 1940s or since the beginning of aviation? Your results would vary dramatically depending on the range of events of the time, I think. You are right to an extent. Yes, the results would vary in that flying fighters would be even more dangerous during war time. During peace time it's only several orders of magnitude more dangerous than commuting. I can echo Ed's comments to the extent that I have known more fighter pilots who died in peacetime than I have commuters who are no longer with us. War is a whole 'nother state beyond that. And you'll find that the ratio was even worse in WW1 than in later wars. Of course, if you are commuting on a motorcycle in heavy traffic, your opportunities to match the modern peace time death rate among fighter pilots are much improved. Jack |

I'm curious to know how the F-100 compared to the 104. I assume the
planes had different missions but being from the same era I lump them together. I've heard/read about the Super Sabre being a handful but comparing the wing on it to the 104's lack thereof you'd think it would be tame by comparison. I figure any of the first-gen jets could be a handful for a hamfisted pilot as high speed aerodynamics was a new science then and quite unforgiving. Would like to hear input from those who've "been there". Wooly |

Well, I've flown neither the F-100 nor the 104. But, I've flown with a
lot of guys who've flown them. My experience was F-105 and F-4. The F-100 was known for it's adverse yaw--the phenomenon of having the airplane yaw away from the direction of intended turn when a lot of aileron/stick is thrown in. Roll hard left and the airplane suddenly flips over to the right. The issue is that the down aileron creates much more drag than the up one--i.e. yaw away from the roll direction. When that happens, suddenly the high wing gets a lot of blanking from the yawed fuselage and the low wing is placed in a better lift producing situation and you go the wrong way. Throw in that the -100A model had no flaps and hence very high landing speeds and a slow responding, relatively low power engine. That, of course leads to the potential for the "Sabre Dance" where you get behind the power curve, extremely nose high and the only way out is to lose altitude which might not be available. The F-104 really was only a problem because of high landing and take-off speeds. (WaltBJ will undoubtedly offer greater insights into the Zipper at this point.) The F-105 had very few bad flying characteristics except for the high wing loading and high TO/Landing speeds. The "hard wing" F-4 (before leading edge slats were added to E-models) had very similar adverse yaw characteristics as the F-100, but a lot better thrust/weight and engine responsiveness. Boundary layer control (blowing) reduced landing speeds as well. |

Ain't no doubt about it. But, for folks who had grown up flying more
docile aircraft, the traditional application of flight controls--stick to turn and rudder only to coordinate a bit--the serious adverse yaw was a killer. The first generation of F-100 drivers were having a difficult time and suffering a number of crashes until North American started a serious training program to visit the various bases and demo the airplane as well as provide details about how to control it--particularly in the final turn. Can't remember right now whether it was Chuck Yeager or Bob Hoover that was the star of the show. Even when I went through F-4 checkout, there were a lot of IPs at Luke who seemed very reluctant to get max performance out of the airplane. The initial impression was of a not very agile platform. Flown properly, however, with little or no aileron input any time there was back-stick, the airplane was very competitive. As you say, rudder was our very best--and most dependable--friend. |
