Whilst I agree that a Cessna 150 is not a great weapon this stunt has done real harm to general aviation in the USA. The aircraft took off from S37 (Smoketown) on route to an airshow. The Washington ADIZ is in the way of a direct routing. It is on all the charts, it is massive and difficult to miss particularly in a slow airplane like a 150. Duats and AOPA as well as others will work out a route for you without infringing the largest TFR in the USA.
There really is no excuse for this bad airmanship. Navigation around the ADIZ or a VFR flightplan through it and contact with ATC would have avoided this mishap. Flight through this airspace is really easy, you get vectored around the place. All you have to do is fly the headings they give you.
As it is the pilot will lose his licence for a long time and many would say deservedly so. General aviation will again lose credibility and we will have to deal with uninformed criticism and further restrictions and overview none of which we need or deserve through the actions of a couple of careless pilots.
I think the actual or perceived risk is irrelevant. It is a no fly zone without a flight plan so stay out if you don't have one. A bad day for GA.
