With 'Before 9/11, it was not unheard of for a commercial aircraft to deviate slightly from its course, or for an FAA controller to lose radio contact with a pilot for a short period of time.', is it rational to deduce 'It wasn't unheard of for a commercial aircraft to change their route a bit, though it is absolutely not allowed today, under any circumstance.'
