Am you legally justified in killing a passenger who refusestoturn off their cell phone?

I do not know much about aircraft cargo holes, but do know a bunch about GBS, EMP, and have worked in screen rooms. I rather doubt that the cargo holes have RF gaskets on all the seams. Bonding of the seams is not the same as having RF gaskets. RF gaskets would add weight to the aircraft. So I doubt if there are RF gaskets. Dan |

So I doubt if there are RF gaskets. How far apart are the rivets in the seams? What wavelength are you trying to stop? Do the math on the attenuation. You can never get perfect shielding, but cell phones don't talk to each other, then talk to a cell tower. I have worked in both screen rooms and the modular aluminum booths. Both types used beryllium copper finger stock on the doors as the seal. The cargo doors on the airplane require a tight seal to keep from losing air. Do you really think a cell phone in the cargo hold can hear a cell tower? -- You can't have a sense of humor, if you have no sense. |
