You need a 4 year education to be a Airplane mechanic and need to pass examinations which Lewis I am sure has not done. Also you can not have a criminal record, which would disqualify him. So the most he could be is someone’s helper, which I just don’t see. With his record I am not really sure he could get passed security which he would need to gain access to airplanes. I just don’t see the government giving that to a twice felon.
