    This picture might be of a privately-owned F-104. Found it on the web.
    Pic was taken at Phoenix Mesa Gateway Airport (AZA) which used to be Williams Air Force Base in Mesa, AZ.
    No country military markings on it.
    Looks like it would definitely be a handful.

    That is a dangerous aircraft!! I wouldn't have the balls to fly one. They're a death trap

    just for fun, a F-104 story (which highlights the F-104's very interesting BLC system)


    Reprinted from: http://www.916-starfighter.de/Hamilton_story.htm


    The F-104 was literally a kick in the butt to fly in comparison to the old subsonic birds we had been flying up until that time. When I say "that time" I am talking about 1957, which is when I started flying the F-104. Going fast was no problem for the F-104 but going slow was, so they installed a BLC system, or Boundary Layer Control, on the airplane. This system enhanced the boundary layer air flow over the F-104's wings, allowing the 104 to be more easily controlled at lower airspeeds, such as take-off and landing. But the new BLC system had its weaknesses.

    On this day I had picked up a new F-104 at the Lockheed factory located near Palmdale. Another jock by the name of Don Dickman was also taking delivery of a new 104. We were both delivering them to James Jabara's squadron at Westover AFB, so we decided to fly across the country in formation. Don and I took off and headed for our first fuel stop at Kirtland AFB in Albuquerque. I was leading and Don was flying wing. Even today that flight is clearly imprinted in my mind because I came within a fraction of a second and only a few feet from being killed during that base to final turn for landing at Kirtland.

    I think I'd better explain a bit about the BLC (Boundary Layer Control) system and how it worked in conjunction with the F-104's wing flaps. The aircraft was built to go FAST and had very small wings (7 feet in length each) and thus a very high approach and landing speed. So Kelly Johnson, Lockheed's famous chief engineer, and his "Skunk Works" guys came up with something new to lower the F-104's approach speed by about forty knots or so. They designed a system which bled-off excess air from the jet engine turbine's 9th stage high-pressure air compressor, re-routing this high-pressure air through small metal tubes integrated into the wings ahead of the wing flaps. These tubes had numerous holes in them allowing high-pressure turbine bleed air to flow out and over the 104's landing flaps to improve lift, increasing the velocity of the wing's boundary-layer air flow and basically "fooling" the wing into thinking it was going much faster. As the F-104 slowed and its wings approached a stall condition (loss of lift), the pilot lowered the flaps to the fully extended LAND position with simultaneous high air pressure from the BLC now delaying the stall and allowing lower approach speeds.

    The 104 had three wing flap positions: UP, TAKE OFF & LAND (T.O. & L), and LAND. A military airfield's 360-degree* Overhead Traffic Pattern was normally entered at 1,500 feet AGL (Above Ground Level) and in the 104 you entered the Overhead at 325 knots indicated airspeed (fast). After passing mid-field over the runway you performed a 180-degree "pitch out" maneuver, then rolled the wings to straight and level after turning 180 degrees to the Downwind leg. The book (104 Flight Manual) said to lower the landing gear and T.O. & LAND flaps on downwind (opposite the direction of landing). Farther downwind, when the end of the runway is approximately 45 Degrees behind your shoulder, you start your descending Base-to-Final turn, pretty much one continuous descending turn, 180 degrees around to the short Final Approach leg to the runway. (*180-degree pitch-out plus 180-degree base-to-final turn = 360-degree overhead pattern!)

    After approximately 90 degrees of the 180 degree Base-to-Final turn, the book said to select the LAND flaps position, where both leading edge and trailing edge flaps extend down to their full 45 degrees of extension, creating more lift at slow speeds, and the BLC air system cuts in, creating even more lift. I did all that.

    But fate reared its ugly head.

    With Don just 5 seconds behind me, I was turning onto final when I moved the flap lever to the LAND flaps position. The flaps neared full-down position while passing through 800-900 feet AGL with 30-40 degrees of left bank. As the flaps neared their full-down position the Boundary Layer Control air system "KICKED IN!"

    Completely on its own, the aircraft ROLLED HARD LEFT turning me past the runway heading and rolling its wings well-past vertical.

    Reacting instantly with full right rudder and as much right aileron as I dared use (due to adverse yaw) I could not stop the left roll. I was quickly going inverted. I thought about ejecting "upward" (the early F-104A had a downward ejection seat and my 104 was nearly upside-down) but the nose was too low...and getting lower.

    I immediately knew the BLC had to be the problem. I slapped the flaps switch up one notch to T.O. & LAND position to cut off the BLC and simultaneously slammed the throttle into afterburner to give me all the thrust I could get. I'd instantly stopped fighting the left roll and used both rudder and ailerons to expedite the forced roll quickly back to wings-level (right-side up).

    As the wings rolled level, I delicately started applying up elevator (pulling back on the stick gently to avoid a stall) until I felt a "burble" (near-stall buffet on the wings) while noticing that the pitot tube on the tip of the 104's nose cone appeared to be threading through the sage brush. Soon the nose began to rise a bit and the aircraft started accelerating and climbing out, away from the ground.

    According to Kirtland's tower controller my afterburner blast was kicking up a terrible cloud of dust. They figured I was rolled up in a ball of fire out there and immediately dispatched crash and rescue crews.

    Circling overhead, Don was amazed to see my beautiful new "Zipper" climb out of that horrible-looking mess down there.

    Don joined up with me and we climbed up to 10,000 feet and took a few minutes to calm our nerves. I then asked for permission to enter the pattern for a straight in approach with T.O. & LAND flaps only, not full flaps, so as to prevent further use of the BLC system.

    After landing and taxiing in to parking the maintenance folks came out and checked the BLC tubes in both wings. Sure enough, the tube in the trailing edge of the LEFT wing was badly warped while the remainder of the BLC air tubes were fine. That meant I was getting full BLC enhanced lift air blowing on the RIGHT wing while the LEFT BLC was not blowing air and this was destroying lift on the LEFT wing.

    No wonder it had rolled hard left...

    I got on the phone to Tony LeVier, Lockheed's famed chief test pilot, and I suggested (read: INSISTED) that Lockheed submit a change to the F-104 Flight Manual and immediately put out a RED LETTERED message to all users to go to LAND flaps (with BLC) while still at 1,500 feet AGL on DOWNWIND LEG, to check for any BLC rolling tendencies, and NEVER wait to select LAND flaps until down lower in the final turn.

    Tony agreed and made the changes.

    In the late 60's when I was doing the Abottsford air show, the RCAF did a routine with 5 F-104's that I thought was the best part of the show. Close formation work, touch and goes, and afterburner passes. That is one of the most exciting airplanes ever. One day when they were making a high speed fly-by in formation one of the airplanes went into quick pitch oscillations. The speed at which the rest of the formation broke away from him was astonishing and there were no collisions. The offending bird had a malfunction in the stick shaker and was grounded for the rest of the show. In talking to a USAF pilot who flew the 104 he told us about the airplane and its limits. One interesting comment was dead stick procedures. The magic number was 245 knots and if the airplane dropped below that , you were riding a streamlined brick that was no longer controllable and it was punch out time if you didn't have 20,000 ft. below you.
    When the 104's were parked, a sheath was put on the leading edge of the wing to keep someone from being cut. It was approaching the sharpness of a dull knife. The wing was built of seven planks of aluminum that were fastened together. The leading edge drooped when flaps land was selected and it took plus 80% throttle to provide BLC blowing and thrust for flight when landing.
    I'll never forget the howling sound when they flew by at slower speeds and made thrust changes. They said that it was intake duct resonance. Great airplane and incredible pilots.

    Do any other planes come to mind with a wing loading comparable to the F-104's?

    Bob......

    I wat about 8 or 9 at the time and living in Soest, West Germany as my dad was in the Canadian army.

    During armed forces day they had 3 of the Canadian regiments out on the parade square and all of us non-soldiers in bleachers watching the festivities. A flight of 3 CF-104's in the natural metal scheme of the day buzzed over the reviewing stand at what must have been 50-100' AGL with their burners on......they were hauling azz and the event is burned into my memory as a result. The sound was unreal and the wooden bleachers shook.

    Interesting. I figured that the "heavies" would be way up there.

    My friend and airport owner Steve Snyder died in his own F86 Sabre

    He crashed doing a low and slow pass after an aerobatic routine for the bonanza guys.

    Anyone who buys one needs to spring for the later models that have slats to lower the stall speed, although sadly I think that Steve may have died because of fuel exhaustion.
