This is the aerial display by the Sukhoi Su-35 fighter at the MAKS 2017 air show in Moscow, Russia, last week. The aircraft has very powerful engines, giving a thrust-to-weight ratio much better than 1:1, and also boasts thrust vectoring nozzles, allowing it to use engine thrust to augment its already impressive maneuverability. Its agility puts most other aircraft in its class to shame.

(EDITED TO ADD: The first video I embedded was taken down. Here’s another, of the same display.)
I’d say the Su-35 is probably the best kinetic-energy dogfighting aircraft out there today . . . although that’s not necessarily a war-winning attribute, in an age of stealth technology, long-range air-to-air missiles and active electronically-scanned radar arrays. Nevertheless, if it comes down to knife-fighting range in future aerial combat, the Su-35 would seem to have a great many advantages.
