What it really highlighted was the extremely poor controls that were in place surrounding the whole air display regime.
You can only feel the utmost sympathy for those lost and their dependents - the pilot should have been grounded in light of the evidence available at the time, his display ticket was out of date if I remember correctly.
The only positive is that it has made the whole Air Display scene safer on a Global level. Much the same way it took the Herald of Free Enterprise disaster to reform the Car Ferry industry, human nature is to be complacent when things are jogging along.
