My thinking is similar, as long as these type of systems - which can directly kill the public - are developed by purely commercial interests with no oversight, they will always do the minimum safety measures to get the $. For some reason a car plowing into people is more palatable than a plane crashing out of the sky.

Agree. Point well made.

I hear you, but, SMS is the farthest from secure you can get - so I can see why they chose not to support it.
