I was thinking this fine morning and the question came to me:
“Who do some cargo airlines operate older aircraft?”
I know the cargo 717 and 727 are very rare, and FEDEX operates the DC-8 and DC-10.
If these aircraft are so old, and parts are hard to find, why are they still operating?
Is it because the airline doesn’t have money for newer planes?
Is it because that there are so many in their fleet that they cannot rid all of them?
