Hah Mongoose, that's pretty good.
F20 has been my fav fighter since the late 80s. Chuck Yeager was a huge proponent of it, and other small, light, cheap, etc fighters. The sortie generation rates of the thing were impressive for the time. Imagine a modern engine in that airframe now - crazy.
I have a couple other documentaries on it bookmarked, on another PC, I'll link them in later if anyone cares to watch them.
The book "Warriors" came out in the early 90s, Barret Tillman wrote it, he's an excellent aviation author and former fighter pilot, and wrote a great book with the F20 Tigershark being the main character essentially. You can't find it in epub/online anywhere, but I've found used paperback copies for 1 cent on ebay all the time. If you like the F20, it's a must read IMO.
The Gripen today has many F20 like qualities - especially the ability to have very rapid turnarounds and sortie rates. Good friend of mine flew the Gripen at Empire test pilot school a lot, 50 hours or so, and really wanted our country (Canada) to seriously consider it instead of the F35, mostly due to cost, but also for capability - it's refueling system matches up with our boomless tankers, the latest model w/ 3 tanks has great range, and a fantastic AESA radar and IRST.
