When that Texas cowboy finally lets loose with 800 cruise missiles/tomahawks a day in a blitzkreig and Sadaam starts firing back I do not want a "smart" missile thinking that nice big warm 747 nearby is its "target". 
In the Gulf War the 'success' rate/accuracy of those missiles was atrocious.

I wouldn't worry about it, since such cruise missles will never climb to the altitude that a 747 flies by, nor are they heat-seekers.
