I want to know the answer to the following question:
Why have many US Air Force pilots opted to resign from active service?
All the background I'm provided with is that "The Commander of Air Combat Command, General Mike Hostage indicated that the USAF must reduce its F-15 and F-16 fleets and eliminate platforms like the A-10 in order to focus on a fifth-generation jet fighter future.". Is that enough to answer the question?
Answer: no
