Planes can and often do land themselves without pilots on board. It's not a graceful setdown, but it's far from guaranteed to be a fireball. They just gradually lose altitude until they reach the ground, which if it is sufficiently flat, they then scuff across until they come to a stop.
Not how it works for jets, where losing your engine is pretty much a guaranteed crash.
Regular (e.g. passenger) planes have massive wings that work with the air to keep the plane in the air efficiently, at the cost of maneuverability.
That's assuming the engines went bad.

Doubt a jet would do that, with or without an engine

Unless, like you said, they lose one or more engines, because military jets generally don't have great glide ratios.
Most new jets are fly by wire (f35 is one of these, where as the link you posted was about an aircraft which was not), they are inherently aerodynamically unstable, below a certain speed it's just gonna stall and crash not glide to the ground. We use computers to manage the instability as the instability aids in maneuverability. Passenger planes and the like are not designed like this, so they can, in theory, just glide down, but the glide slope is what will determine if it's gonna be a soft or deadly landing.
Yeah but they're going to hit some bumpy ground or a tree or a car or a cow or a house or something. It's not exactly a flat landscape up there
