AVM David Walker may well be a nice chap...but let us be accurate....he is a "new" GD Branch officer..as all crab officers are above the rank of wg cdr these days. He is not and never has been aircrew and as such would not have been a GD aircrew officer of the old style. Nice sinecure he has
though....wonder where he parks his car when at work and does he pay the daily congestion charge?
