Cyl 8 Coil/plug popped out?!?

[Dr. Apex]

Well, I literally am just getting into Phoenix from Ohio, and I hear a bang and huge noise of venting atmosphere on I-17 just before Happy Valley rd. I stop and find the coil and plug(still attached to the coil) loose and off the head and I'm venting cylinder 8. Took it out and everything looks relatively ok, coil is damaged from hitting the fuel rail, plug has 2 slightly bent threads, and the thread in the head I'm waiting to hear if it's ok or not but it seems so.

Anyone ever have this happen? Possibly just the plug not tightened enough when it was changed last fall?? Were going to check the rest of them and make sure they're ok. I limped the car into Masterwerks Auto on 19th ave, talked to Hank from the board here and says says they're a good shop which makes me feel better.

Cyl 8 threads are stripped out, thanks to the idiot who installed the new plugs last fall. Attempting a helicoil for repair.
