This is a on a 2016 1.6L Ford Escape. In picture 1 you can see the spark plug in trouble - it is too deep for some reason, we got the old one out but when we put in the new one, it fell too deep. The second picture shows what it is suppost to look like and it clearly looks different.
I already tried to use a magnet but we tightened it before we noticed what happened so it won't come up with a magnet.

if you tighten it, the socket must have gone down with the plug, and if that is so, then the socket should go down to it again. if not then I would say it isn't tight/threaded into the head and maybe you can just pull it up with vise grips on the terminal un-threading while lifting. I agree that there could be a thread insert that came out on old plug.
The plug could hit the piston if you crank it and do damage.
You’ll need some kind of vacuum & hose that fits tight over the insulator to pull it out.. try some plumbing pipe reducers on a shop vac.with a rubber garden hose. Improvise.
