dividuals FCC did pass Docket 20l20 According reports FCC offi cials did realize us partly because lot people use club licenses cost FCC license $20 justification using club license approach However now five-year license $4 should have individual licenses let FCC know around still think club license has its place en abling beginners get airplanes air waiting individual licenses processed FCC club
