Can Static Electricity Penetrate a Faraday Cage?

Click For Summary
Static electricity cannot penetrate a Faraday cage, which effectively blocks all electromagnetic fields. However, static fields can be generated from within the cage itself. The discussion also references the phenomenon of ball lightning, which has been reported to enter aircraft through windows. A model demonstrating static charge entering a Faraday cage is provided for further understanding. Overall, while external static electricity is blocked, internal static charges can still occur.

please forgive a not very scientific question, i am wondered if static electricity can penetrate a faraday cage, this has to do with ball lightning being seen in an aircraft.

Nooooo... a Faraday cage blocks out all electromagnetic fields.
 
Unless you mean if static fields can be generated from the inside of the cage, the yes, you can.

I've heard of ball lightning passing through the front windows of aircraft into the interior.
Try this for a model of static charge entering into an opening of a Faraday cage:
