C'mon boys and girls, use your heads. The NOTAM system is perfect in all respects. That is, it's perfect to protect the backsides of everyone except the pilots. "Captain, why didn't you read the NOTAM related to xyz on page 3 the forty fifth line down? It was right there in front of you." So the airport is covered, the dispatchers are covered, the managments are covered, the ATC system is covered. And of course you are covered if you can read jibberish at 3am in the morning and remember everything 7 hours later.
So why would anyone ever want to change it? It hangs the pilots out to dry, but everyone else is covered. Watch your six.
