SF, no I'm not. I've never set foot on a UK E-3D and only ever visited Waddo a couple of times. I also retired several years ago. I Just find the continual whinging, carping and criticism from certain quarters both boring and pathetic.
I haven't the experience or expertise to comment and compare the ability, or experience, of the two forces. But I note it is always the ISK guys doing the knocking of other serving RAF personnel, who seem to be fulfilling a vital role, and doing so extremely well.
The end effect is to diminish my respect for the ISK force and increase that of the Waddo force. I'm afraid Sandy and his ilk are doing the reputations of themselves and their fleet no favours here.
