Some who work in the airline industry worry the government shutdown could have an impact on safety.
Thousands of FAA inspectors have been furloughed during the partial shutdown.
Some worry losing the extra sets of eyes could increase the risk of problems.
The impact is already being seen on newly-acquired planes and other aircraft.
Inspectors say federal oversight of airline operations.
Delta employee, David Richard, said "We have airplanes waiting to go into service, and that's holding them up."
Also furloughed FAA Safety Inspector, Bill Hoogenhout, said "It's a second set of eyes that are missing that will, in my opinion, would escalate risk."
The FAA is recalling more than 600 of the 3,000 furloughed inspectors.
