I was reflecting on 9/11 a little bit earlier by listening to some ATC recordings as the events unfolded and it brings up a question that I’ve often wondered. Let’s say you hypothetically find yourself intercepted by F-16’s. In reality, what can they do? They don’t have control of your aircraft, so the term ‘intercepted’ doesn’t seem totally accurate. The ATC tapes from 9/11 had a couple instances where they called for some F-16’s to scramble and intercept the hijacked aircraft, but I don’t understand how that would’ve made any difference in the outcome. So they have fighter jets trailing them, so what? The hijackers are still in control of the aircraft and will still do what they want, so what are the interceptors really accomplishing aside from being able to better see the aircraft and what it’s doing?
