Could it be that, while both are certainly tragic events, the media attention surrounding airplane crashes is perceived to be greater? And the potential collateral damage is probably going to be greater also?
There's no perceived about it- it -IS- greater. If a bunch of terrorists shoot up a mall or blow themselves up in a mall, all the media whores get is a picture of a building with a crapload of LEOs, ambulances, and yellow tape around it, because a building can get cordoned off pretty well. It doesn't make for "good television." A burning plane (parts) or a burning building, etc, makes for "good television" and that's also what the terrorists want. Compare something like the VT massacre coverage to say, the coverage of a commuter plane crash. Basically the same amount of dead people but the plane crash gets more "blood and guts" type of attention because there are usually witnesses all over the place, parts of aircraft, maybe burning structures etc that can be filmed, etc.
There's also the associative effect. If a terrorist attacks a mall a lot of people I know are not going to identify with that, because they spend little or no time in shopping malls. On the other hand, with an airplane, it's less of a leap for joe viewer to say "that could have been me or someone I know". The fact that planes violate geographical boundaries also adds to this. There is no "it can't happen here" BS with airplanes because airplanes fly all over the country. "Emotionally" it is difficult for people to write off airplane tragedies. It is also easy to opt out of going to a mall. It's not so easy opting out of air travel. This makes it harder for people to emotionally write off an incident, even if the odds in either case are slim to none that they or someone they know will actually die of terrorism.
Here's another example. Say a bus full of people careens off a cliff in the rockies and a bunch of people die. Then a commuter plane carrying about the same amount of people crashes. Which do you think is going to have more media attention.... the plane, of course, with all its flaming wreckage, ATC tapes, and all sorts of other hyped up drama.
The terrorists know that american media whore outlets love burning planes and other crap like that. Additionally, they also know it is harder for the authorities to "containerize" those kinds of disasters. For example if there is a mall shooter that kills 30 people, all the TV whores get to run is pictures of what the mall normally looks like inside and a pic of the mall with a cordon around it with a bunch of LEOS/FF/EMTs outside. There is no "gory burning wreckage" to film, just a boring building.
Another thing to add.... let's go back to 9/11 for a second. People probably know some of the names of the people who died in the hijacked plane crashes. On the other hand, a lot less people know who the many, many other victims were that perished "on the ground" at the WTC and Pentagon sites. This is all because the media whores are obsessed with mangled aircraft and explossions and such. It's almost right out of hollywood. The media whores think they are like Michael Bay or someone like that, except someone else is directing the action. (terrorists and psychos).
As a disclaimer, before anyone thinks I'm like trashing the right to free press, etc, I certainly am not... I'm just exposing the reality of american media whoring. It is what it is, and we also have to understand that the terrorists are "marketing their acts" to obtain the widest exposure... and that, is through air disasters. Every media whore loves a good old fashioned air disaster of some sort or another.
Would a suicide bomber in a mall cause those effects? Yes, I think it would, but even if a suicide bomber kills 30 people in a mall the media whores have nothing to show on television, except for a talking head of "Big Sis" telling us how we need to remain vigilant or some crap... and even the sheeple are not going to keep their TVs tuned into Janet Napolitano for any length of time, lest their eyes start bleeding. On the other hand if you turn on a TV and see a burning plane, the average reaction is "oh wait, lets see if there is MORE burning plane footage!!! " etc.
There's also the "prize effect". Terrorists see value in hitting what people falsely believe to be an "untouchable" target. If they drop another airplane it is kind of a deep blow to america, as the government runs this huge facade of "tight airplane security"... so the net terror is greater because people will feel more vulnerable. A soft target getting attacked can be written off as a one off, on the other hand there's this weird, BS nostrum that "air travel is safe from terrorism because of all the security" which is a bunch of crap.
