So now we have the crux of this problem which is much wider than the Shoreham accident.
Why, for years, have the CAA allowed civilians to fly displays in ex-military fast jets when they are barely current on type - let alone current at carrying out a low level aerobatic display?
Surely, these jets should be flown by professionals in a BBMF-type 'Squadron' properly funded so that currency, engineering etc are not a problem.
