OK, I've been tempted to say this. People who no nothing about operating small private planes, and most especially out of small private airports, seem to think that the failure to "file a flight plan" is some kind of cardinal sin. That's a load of crap! Flying for pleasure very often does not involve traveling along a narrow, prearranged course. The "talking heads" of the mainstream media are probably the worst offenders in implying that failure to file a flight plan is the root cause of flying accidents, but, please, let's not fall into their mindset. Yes, a flight plan that's rigidly adhered to would make life a bit easier for search and rescue personnel sometimes, but there are many reasons not to fly along one's proposed course, and most are good ones.
