The graphs show a slight instability, if you cant cope with that level of divergence in 3 minutes then my guess is you'd either be paralysed or in a coma.

Wow....

In 10 seconds the aircraft changed speed by 40 mph.....

After 3 minutes, left to its own devices, the aircraft was changing speed 110 mph and on it way to self destruction.

The oscillation grew larger by 20mph to 40mph each cycle.

A cessna 152 will change that much in about as much time, luckily most people wouldn't be doing 'nothing' after 3 minutes.

BALONEY.

It will dampen the oscillation and the speed change will be non-existent in ~ ONE MINUTE.

Yes a cessna will stabilise quick, you missed my point, we are talking about the Spitfire here, the oscilations that your graphs show are really not vicious, while the cessna is in the process of stabilising I have seen speed fliuctuations of a similar magnitude, of course they are decreasing but a 40mph change in 10 seconds is miniscule, a half dead monkey with no flying training could catch it even if the amplitude was increasing.

You missed the point.

The Spitfire will not stabilize, it will get worse.

That means constant correction and pilot attention is required to fly the plane.

As for the other contention, only the paraniod pointy tin foil hat crowd see this as some kind of attempt to "pork" their favorite gameshape.

The results are measured. I find it very amusing that and quite telling the individuals who cannot accept the results for what they are but insist upon some sort of reassurance to calm their fears.
