(I know I used the Super Yeger as a base, but it's a much better base for a plane like this)

A Yeger (or Super Yeger) Absurdly modified, with practically everything being changed.

History

Year: 1961

IAN needed new planes to replace its older fleet, but the demand for modern planes was high worldwide, which made it difficult to acquire new planes.
The NV-61s started production a year earlier, but due to lack of materials such as titanium, it was taking a long time.
Most of LAN's aircraft fleet was made up of the F1-NE Yeger, which was already terribly outdated, especially after a fight against an air force in which there were the F1S, which became a terror in the skies
The IAN didn't have enough NV-61s, and had most of the fleet made up of an outdated plane.

So an idea was proposed:
Extremely modify the Yeger, making almost a new plane
The proposal was accepted and a Yeger was modified to meet the proposal, and after some tests on the ground, the plane finally flew, but it was not supersonic.
After 40 subsonic flights, the plane would finally go supersonic! The plane then took off, went to about 8000 meters, and then turned on the Afterburner and thus passed Mach 1.
After the cone disappeared, the pilot continued, and reached the speed of mach 1.1
But the plane was still accelerating, so the pilot didn't stop.
But, after exceeding the speed of mach 1.2, the pilot contacted the radio:
"Sir, the plane is vibrating a lot, and the controls are very tough"
Then all of a sudden the controls stuck. The pilot used the trim to bring the plane down and turned off the Afterburner. But the controls didn't unstuck
The pilot said on the radio:
"I can't make turns with the plane like this, how am I going to land? I can only go up and down and the trim doesn't work at low speed, and the fuel is low, I think I'll have to eject"
After a few minutes, the controls did not return. And as fuel was running low, the pilot was allowed to eject at a location close to an allied carrier.
The project then went back to the drawing board and the problem was found.
High speed vibration was due to a slight error where the wrong oil was put in the engine
And the controls lock was caused by vibration, which caused the plane's hydraulic system to fail.
And then the hydraulic system was changed to a more resistant one, and the engine stayed the same because wrong oil is not an engine reliability problem
However, demand for modern aircraft had waned, and mass production of NV-61s had begun.
All this culminated in the loss of the need to modernize the Yeger, and the project was canceled
The plane that hit the water was recovered and repaired, after which it was placed in a museum, but due to a robbery the plane was destroyed and thus ends this long description.

AG1 Opens the cockpit
AG2 Afterburner

Fun fact:

The plane really starts to shake at high speed
