I just finished my CFI and CFII at the Fort Worth AF office last month and now I work there. It took me about six weeks to get them both, but I was delayed due to lack of FAA examiner availability around Christmas time. I could have been done in a month, but I was there 9-5 six days a week working at it. We are short on instructors, but I don't think it is affecting student output (yet), we are just working longer hours. If anything, I think we could use a few more planes.
