Not in our lifetime. A terrorist could still at least crash the airplane by internal destruction of systems, wire bundles, etc.
With the US government's willingness to shoot down hijacked airliners and murder the crew, pax, and terrorists, why don't they just put a self-destruct package on all commercial aircraft that can be triggered by remote control from some military command center. Saves the cost of an interceptor's jet fuel.
Just when you thought it just couldn't get any more stupid . . . .
