This looks to be the Air Training Command parking area except for the B-57. The 737 is probably a T-43, which was used for navigator training from about 1973 through ~2000.
The small trainers in the rear are T-37 'Tweets', which was the primary USAF pilot training aircraft for generations. These have been replaced by T-6 Texans. Off to the side are T-38s, still used for advanced pilot training..
