  •  YF-16 and the F-16 have good safety (0+ / 0-)

    records compared with more complicated designs.

    Note the absence of comparison with F-15 and the rest.

    F-16 is flying pretty good. It is not an unsafe airplane. BTW: to understand fly-by-wire and stable/unstable designs:

    FLY BY WIRE. From the outset, the YF-16 had no direct connection between the pilot's controls and the aircraft's control surfaces. Instead, the stick and rudder controls were connected to quadruple-redundant computers, which then told the elevators, ailerons, and rudder what to do. This had several large advantages over previous systems. It was quicker responding, automatically correcting for gusts and thermals with no effort from the pilot. It could be programmed to compensate for aerodynamic problems and fly like an ideal airplane. Most importantly, it enabled, with full safety, a highly efficient unstable design.

    NEGATIVE STABILITY. All previous aircraft designs had been aerodynamically stable. That is, the center of gravity was well in front of the center of lift and the center of pressure (drag).

    To illustrate the difference between stable and unstable designs, take a shirt cardboard and, holding it by the leading edge, pull it rapidly through the air. It will stretch out behind your hand in a stable manner. This is a stable design Now take it by the trailing edge push forward from there. It will immediately flip up or down uncontrollably. That is an unstable design.

    That's Federation of American Scientists.

    Is this a shill diary ? Trying to build a case for another super expensive fighter buying program -- while we've got 900+ reasonably good F-16s and damn near no use for that many of them ???

    And yes, I knew John Boyd. Like the design. Always did.

      As it's said about falling, it's not the flying that's the problem.

      For those 312 F-16's which were destroyed upon their uncontrolled return to the ground, it's the crashing that we should consider when judging it's safety.

      Your assessment of the diary's intent is no better than your assessment of F-16 safety.
