Well, not in the US. There have been civilian airliners shot down by militaries in other parts of the world. Maybe by mistake, maybe delibrately, but I’m not sure we want to go into an exhaustive analysis of that in this thread.
I say, from my own personal observation, there are a LOT more civilians eager to shoot down airplanes (of any sort) than military.
Fact is, since 9/11/01 there have been hundreds, if not thousands, of violations of various restricted airspace and not one airplane has been shot down. Lots of intercepts, no shoot-downs. This, despite the fact it no longer requires Presidential permission to do so - the capacity to make that decision has been distributed to certain individuals still high in the chain of command, but no longer at just the very top.
Those who have the actual guns are less eager to use them than some of those who don’t.
As a recent example, during the Week of Reagan’s Wake a King Air 200 without transponder signal entered the restricted airspace around DC, making an apparent bee-line the city center. Needless to say, while the secret service was evacuating the Capitol and telling Deborah Norville (among many others) to take off her high heels and get running jets were scrambled.
About this time you might be saying “huh… I don’t recall hearing about a shoot down…” That’s because none occurred. It was quickly determined that the plane belonged to the State of Kentucky and was carrying the governor to Regan’s funeral. The transponder, although correctly set, had malfunctioned while en route to National airport (in other threads I have pointed out that transponders DO fail).
In this case, had it been necessary to shoot down the airplane could it have been done? The answer is yes - armed fighters were scrambled in time and did intercept the airplane. However, one pricipal of responsible gun use it to be sure of your target. It was quickly determined that the airplane was no threat. It did, in fact, have the necessary permissions and waivers to be in that airspace, and the plane was permitted to land. I actually find this whole incident to be reassuring in a bleak sort of way - the system worked. Whatever deficiencies or oversights lead to the carnage 9/11/01, some remedies have been applied. It will be much, much harder to pull the same stunt again, yet there are also safeguards to help prevent the gunning down of innocents.
Although I wish the authorities had anticipated better, I can forgive them much in regards to a situation that had never occurred before. We do not have perfect foresight. What I do ask is that people learn from a tragedy, and apparently that has occurred.
I will, however, point out that if it had been necessary to shoot down that King Air over DC, given the point of intercept, it would have been over inhabited territory. A King Air isn’t particularly big - even if (very hypothetically) it had been loaded with explosives the damage wouldn’t be anywhere near what would occur with an airliner - and the damage would be no greater than that of any other plane crash of similar size.
However, an airliner is much bigger and significantly faster than a King Air. If it had been a hijacked airliner (which would have required subduing a planeload of passengers and breaking into a fortified cockpit these days) the intercept might have occurred later - or perhaps not at all.
I think folks may have to get a grip on the fact that under some circumstances, even today it may not be possible to intercept a big, fast airplane before the damage is done. I’m sorry, but that’s the truth as I see it. It WILL be much, much harder to do a 9/11 style attack, but it may still be possible.
Yeah, I think that’s the most likely outcome, too - of a *commercial airline * hijacking. There are alternative ways to get control of a big Boeing or Airbus, though.
I doubt it. How do you define “small”? Four seat piston planes? No way - they just don’t have the payload to carry much. You would get a very limited amount of damage. Frankly, the average sedan size car can carry more weight than a four-seat airplane and makes a much better bomb. King Air? Yeah, that’s bigger - imagine loading a bus with bombs, something like that. No question that’s bad - but the 1993 attack on the WTC was what, a panel van filled with explosives? Sure, it did some nasty damage but they cleaned up the mess, fixed the damage, and went on with life. It’s not a big enough blast to take down something like the WTC. Sure, a smaller building would be destroyed, but again, it is so much easier to load up a Ryder van with fuel and fertilizer and park it in front of your target. Small airplanes are (as far as I can see) not nearly as useful for this sort of thing as cars and trucks
Which is not to say small planes couldn’t be used by terrorists - we know the 9/11 crowd used them for training and for reconnaissance flights around/above their chosen targets. But think about it, people - Mr. Atta and friends routinely rented small airplanes, flew them, used them - for a mere $30,000 or so you can BUY one. Why would they have gone to the trouble to hijack a 757 unless necessary? It’s so much easier to just *rent * a small airplane - $80-120 an hour, depending on location, navigation equipment, and horsepower. Nope - the only reason they hijacked a big plane was because they needed something huge to do the job.
Yes, hindsight is 20/20 or better, and arm-chair quarterbacking is easy, but I can’t find it in my heart to demand heads on platters for 9/11. Going forward, however, I expected changes, and changes have occurred. I expect Al Qaeda’s next attack to be something different than a hijacked airline. With so much attention devoted to aviation security other potential hazards have been ignored, leaving us vulnerable in other areas.
