You can do it, but you need some way to miss the rocks on the way down. If you are an expert at using a paraglider then it’s possible and it’s been done, first time in 1988 by Jean-Marc Boivin, It can probably be done with a wingsuit too, at least Valery Rozov thinks so, he did a wingsuit jump not from the summit but from 200 meters above the north col. So you can probably do it by wingsuit for the first bit and then parachute to land softly.

So, first, you can use a paraglider, here is Jean-Marc Boivin first to paraglide off Everest in 1988 - he flew down from the summit of Mount Everest and flew down to Camp II at 5,900 meters, so nearly 3000 m below the summit, in 11 minutes.

Then, this is not Everest itself, but from the col connecting it to its northern peak Changtse.

Valery Rozov in 2013, glided with a wingsuit and then parachuting the last bit, this is from Changtse so part of the same massif - it’s on the Chinese / Tibetan side of Mount Everest, connected to it via the north col. It’s 7220m above sea level, the video says he jumped from Everest - strictly speaking it’s from the Everest massif, or part way up the North peak of Everest.

Here is Changtse in relation to Everest

Changtse - Wikipedia - this map is inverted, North is down. He explains that he jumped from 200 meters above the north col towards the Changtse summit, and that he thinks a wingsuit jump from the summit of Everest itself may also be possible for some future adventurer.

He’s also jumped from 7,700m Mount Cho Oy.
