Some F-15's do have hooks.
"The most outstanding Eagle save was by a pilot from a foreign air force. During air combat training his two seater F-15 was involved in a mid air collision with an A-4 Skyhawk. The A-4 crashed, and the Eagle lost it's right wing from about 2ft. outboard. After some confusion between the instructor who said eject, and the student who outranked his instructor and said no, the F-15 was landed at it's desert base. Touching down at 290 Kts., the hook was dropped for an approach and engagement. This slowed the F-15 to 100 Kts, when the hook weak link sheared, and the aircraft was then braked conventionally. It is said that the student was later demoted for disobeying his instructor, then promoted for saving the aircraft.
McDonnell Douglas attributes the saving of this aircraft to the amount of lift generated by the engine intake/body and "a hell of a good pilot".
