Look at the smoke trails those MiGs leave compared to the F-16s. Interesting, I'd always heard that Soviet/Russian engines were smokers but I thought they'd corrected that in their more modern planes.

The fact is, that these F-16s are brand new ones, whereas the MIGs are around 20 years old.
They are smokers and that only gets worse when you detune the engines to increase time between removals.
