Sounds about what I was thinking, although with my limited EE knowledge I
figured I didn't know what I was talking about. Others have chimed in about
how heavy the shielding would be, but simply putting a copper shield around
the passenger compartment couldn't be too bad. Same thing with the mesh to
diffract any extraneous signals - if it's good enough to keep several hundred
watts of microwave radiation in my microwave oven and I can safely stand near
it, how hard could it be to adapt to an airplane window ? :)
