This doesn't follow. Not even fighter jets were inherently unstable before modern control electronics. Using the electronics to make the flight characteristics better is not the same as the airframe being inherently unstable.
- sandworm101 8y agoThere were stable at altitude, but at low speeds those "fighter jets" became very twitchy. Delta or swept wings are a problem when low and slow. Their landing speeds were sometimes extreme and/or their angle of attack so high that visibility was an issue. Fighter jets are also, in comparison to airliners, not very aerodynamically efficient. They can be fast but burn lots of fuel while doing so. They are like a motorcycle compared to a bus.
