With regard to your comment about not spotting other traffic because it is too fast, sorry but it is not true, unless you don't look out, in which case relative speed is largely irrelevant.
This is nonsense. The relationship between closing speed and the probability of detection is clearly demonstrated in a number of papers on the subject, and is obvious if you stop to think about it for a minute.
At a closing speed of 7.5 nautical miles per minute, the Tornado would have been about a mile away just 8 seconds from impact. A Tornado head-on at a mile has an angular size of about 1/1000: in other words it's like trying to spot a stationary penny from about 30 ft away.
The biggest threat to GA is from tabloid-readers who have no understanding of
risk and its implications for transport safety. The second biggest threat is from pilots who believe they are superhuman, and will continue to protest that they are superhuman all the way up to the point that their rights to fly are finally taken away by regulators who realise that they are not.
