Pentagon Wants Kill Switch For Planes
mytrip writes "The Pentagon's non-lethal weapons division is looking for technologies that could 'disable' aircraft, before they can take off from a runway — or block the planes from flying over a given city or stretch of land. The Directorate's program managers don't mention how engineers might pull off such a kill switch. But, however it's done, they'd like to have a similar system for boats, as well. They're looking for a device that can, from 100 meters away, 'safely stop or significantly impede the movement' of vessels up to 40 feet long, with 'minimal collateral damage.'"
There was discussion on Slashdot about the Soft Walls Project that did something similar. See the 1/04 and 7/03 discussions.
What I find interesting is just how vehement software engineers and pilots are about the idea, and yet everyone seems to trust fly-by-wire.
There is Soft Walls FAQ that covers common objections.
A "kill switch" as of now means an F-18A intercepting it and shooting it down.
The term "kill switch" was a journalistic flair added by Wired, and doesn't actually occur anywhere in the Request for Proposals.
If the door opens inward, it cannot be opened during flight due to the pressure difference between the in- and outside of the craft.

Not correct. The jeep they used was filled with propane canisters, petrol and nails. The Ammonium Nitrate acts as an oxidiser, and these guys didn't have it. Propane canisters are designed to not explode. The Glasgow terrorists clearly thought that if they just lit a fire under one of them it would explode (playing too much GTA methinks). They didn't even attempt to make proper explosive with an oxidiser.
You must be from the UK. That was the IRAs favourite bomb making mixture for a long time. Typically it was a transit van filled with oil drums containing a mixture of diesel and fertilizer (about half a dozen drums normally). I saw a video of such a truck going exploding once - I wouldn't like to be near that!
I used to have a better sig but it broke.
