Um if the spark plug blew out of the cylinder head your going to need to repair the threads...also this is a ushually caused by an extreme detonation which means you have also probably seriously damage other components in the engine.

spark plugs are normally screw into the cylinder very lightly. It normally don't pop off like that. But it happens to your car. These are some of the reasons for that.
If you just change your plug, the vibration under the hood might unscrew it.
Or somebody over tighten you plug and weaken the thread and now pop off after a long time under compression.
Last, a bit of the engine broke off inside your cylinder and push the plug out during the compression stage of the cylinder. You can check all this buy looking at the plug. If the thread is undamage than it is the first broblem(scew it back and you are good to go) check the thread of the cylinder head if that is bad, Sec. problem. If the ignition end of the plug damage, like somebody hit, you have the third problem. If you have the last two problem it cost a lot money.

To be on the safe side replace all the plugs. Make sure you space the ignitors to spec, usually shows in the car manual. Make sure that you put some thread sealer/lock tight on the middle of the spark plug thread. Tighten the spark plugs down til snug and you will be all right, never over tighten or risk the plug being stuck in the socket. It popped out because it was not locked into the socket properly, the lock tight will prevent it in the future.

Spark plugs are threaded into the engine block and won't just "pop out". You were lucky that the plug didn't fire and hit the underside of your hood (and lucky yet again that it didn't go through!). Have a mechanic check the spark plug and the block to see what happened. It is likely that you stripped the block when what can only be assumed to be a poorly seated plug came out. If that is the case, your mechanic can fix the block to receive the new plug safely.
Whatever you do, don't seat the thing yourself without checking the plug threads on the block. When you do put in a new plug, pay attention to the torque requirements.

I have seen this several times, seems to happens on Honda Accords 4cyl. that were not tight enough when car was made and over a period of time the plug loosens with vibration and then its blown out from combustion..or if the plugs have been replaced due to tune up, then it was not installed properly or tech forgot to torque plugs to recommended specifications..either way..look at the plug that it blew out, check threads for damage, and check the plug hole for damage..if none then make sure plugs are the correct ones for vehicle and that they are all alike, and plug is not damaged, reinstall it..

Spark plugs fail. The porcelain insulater can blow out, or the entire plug can vibrate loose and come out. Screw in a new one and get on with life.

Time for a tune up. It will be just fine. Make sure your new plugs are not to long in the chamber.

Nothing is wrong its cause the plug was not put in right. when putting in new plugs you are suppose to tighten then run engine till it gets hot, then recheck and tighten plugs again.
