A lot more information above, the pilot had an unspecified emergency, set the jet onto autopilot and punched out, his companion pilot kept station and followed him down to make sure his ‘chute had opened correctly and he landed safely. Meanwhile, the F-35 carried on flying, its transponder was switched off, so ADS-B has no track, and of course, it’s a stealthy aircraft! Scroll down to the comments, definitely worth a read.
I believe it was fly NW, away from the coast, but America is sodding huge, and if it came down in a forested area, then it’s probably almost invisible from above.
If they ejected at altitude then it could have gone a reasonable distance before crashing.
There was an nutty example of a soviet pilot ejecting and the fighter flying another six hundred miles before eventually crashing after running out of fuel.
There was an incident just after WW2 when an American bomber flying over southern England got lost, so the crew set its autopilot and baled out, leaving the plane flying all on its own. That is, until a piece of high ground a couple of miles outside of Chippenham got in its way…
It was apparently a Convair B-36 ‘Peacemaker’, the world’s biggest bomber at the time, and nuclear capable.

According to a published newspaper report (“Wiltshire Gazette & Herald” 6 February 2003):
“6th February 2003
Bomber flew 30 miles without a crew
FIFTY years ago on February 7 one of the world’s largest aircraft crashed near Lacock, and the crash remains unexplained to this day.
Chippenham historian Paul Moran who has compiled newspaper reports of the accident and talked to witnesses, says the B-36 bomber, carrying top secret military equipment, flew 30 miles over the north Wiltshire countryside without pilot or crew, before plummeting to the ground.
The plane could have crashed in Chippenham with a heavy death toll but fortunately it came down in an isolated location at Nethermore Woods, near Pitters Farm, at Sandy Lane
