This is a photo of my Wife standing next to the sole surviving F20 Tigershark Prototype at Edwards AFB in 1985. The upper right inset photo is of the "N" Number: N44671, the lettering was only a few shades different from the plane body paint.

On this day this Tigershark was flown for a private viewing of military brass and some dignitaries. I believe it was flown by Chuck Yeager for this presentation.

The F20 Tigershark Program is very unusual in that it was Totally Funded with Private Funding.

There were 3 F20 Prototypes produced. 2 Crashed with the loss of the pilots the third is on display at The California Science Center in LA. The F20 never went into production.

An actual F20 was never seen by the public that I know of. Only photographs were made available.

Sorry I did not mention this in the original posting, did't think it was of value to the jest of the posting.

My Wife was married to her prior husband while at Edwards who was a Master Sergeant and was responsible for electronics and autopilots for prototype and upgraded aircraft.

He worked with Fairchild on the T46 project side by side seated trainer. He worked with Boeing on electronic modifications and upgrades to the C-130 Gunship. He was hired by Boeing when he retired. He passed away from cancer a few years later.

She believes he also worked on the F20 while it was at Edwards.

She said he assisted with emergency electronic repairs on a SR-71 Blackbird at Edwards, has photos of him with the Blackbird in the hanger.

The Tigershark was supposed to be an outstanding aircraft...not only a follow-on the F5 Tiger but competition for the F16 for international sales. The US Air Force wasn't interested and other nations that bought F5s in prior years didn't want an aircraft the US military didn't use.

It was a shame...the Tigershark was supposedly a fine aircraft and deserved a better fate.

Reading between the lines of the whole Tigershark debacle, I reckon some, if not all, of the following factors apply.

1) The Air Force were reluctant to help promote the F-20 in case it meant they had to support another type.

2) The F-20 looked too much like the old F-5. I think the USAF and the overseas customers balked at that. Not enough new and sexy factor.

3) GD/Lockheed did a lot of lobbying (maybe even the dollar kind?) and were quick to point out that F-20 looked like the F-5.

4) Some thought Northrop was double dipping. After all, they had the B-2 contract.

The F-20 was on static display at an airshow open to the public at Edwards AFB in 1985, at least. I wuz there.

Along with some other cool stuff.

HiMAT - Highly Maneuverable Aircraft Technology - built by Rockwell International (the company I worked for). Essentially the coolest RC aircraft then existing, it had interchangeable flight surfaces to test out various configurations at a relatively low risk and cost.

This was a scissor-wing testbed, I forget who built it. The concept was a simple method to build an aircraft that could have a pivoting wing that was a straight wing for takeoff and landing, and a swept wing for high speed flight. The trick was that the left side was swept aft and the right side was swept forward. Despite the novel configuration it's my understanding that it flew very conventionally. I nearly got involved with a version based on the much larger F-8 Crusader, but it never came to fruition. (The HiMAT is in the background.)

This was the Grumman X-29, a highly maneuverable technology demonstrator that had a forward swept wing and canards. It absolutely had to be flown using digital controls, no pilot could manually keep the forward swept wing from experiencing "catastrophic divergence" during flight.

I was on temporary assignment at Rockwell in Palmdale from my home site in Tulsa, to do some RAS/RAM work on the newly revived B-1B program. Some of my work was done on base at Edwards. Very cool times for a young engineer. This was one of the four B-1A predecessors.

Back in the 1980s, General Yeager used to do an appearance every October at the National Air and Space Museum, around the anniversary of his sound barrier flight (October 14, 1947). People would wait in line for hours to get the free tickets to these events, and the IMAX theatre was always full.

Billed as a "lecture", it was really just Chuck Yeager telling stories about flying. He was salty, funny, warm, and very blunt. When he was finished, they would open the floor to questions.

One year, a young man in the audience stood up, and in a voice dripping with sarcasm, asked General Yeager to explain just exactly why AC Delco spark plugs were the best ones money could buy. My jaw dropped, and I think most of us in the audience were shocked and offended at his discourtesy.

Yeager took it in stride. He told the young man that when he started flying combat missions into Germany, escorting bombers, they had to keep the RPMs relatively high on their Mustangs to keep the plugs from fouling. Then, he said, one day his crew chief showed him a new spark plug, made by AC Delco, that had a copper electrode. We all laughed when Yeager said that copper electrode shined like a "diamond in a goat's fanny". He explained that with those new spark plugs, he and his comrades could lower the RPMs on their P-51s...which caused them to use less fuel...which extended their range...and allowed them to stay longer with the bombers...which saved bomber crews' lives. And that, he said firmly, was why he was proud to do those AC Delco commercials!

He got a standing ovation for that one, and I remember thinking that the General had just downed another adversary...without firing a shot! :)
