There's this Easter egg where of you go near a emoji textured block in the pyramid of ET it says: "something ancient has awoken" and the pyramid starts to move up and it always breaks the plane cause I can't escape fast enough (send me the Link to that plane) (info about the flying pyramid: there are 9 engines and thenmiddle one is biggest and it has the ion engine thrust from a early version of simplerockets2 or did they use the alien engine thrust for that?)

It's quite difficult to get out in time, and I don't think any of the stock planes can do it. You can kind of just cheat it by changing locations (probably to the midair "Pyramid of Et" location) and then pursue it from there.
