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:
