AA777-200 - Glad I'm not banging my head against a brick wall
As an aside;
At Gatwick passengers travelling on Domestic flights obviously don't have passports as a means of ID.
When you first pass through security, your photo is taken, and the image is storded on computer. A barcode is stuck onto your boarding card.
At the gate, the barcode is scanned, and your photo appears on the screen. The security staff have an almost foolproof method of checking that the identity of the person who passes through security, is the same one who boards the aircraft.
Heathrow and Amsterdam are trialling identification of the iris. If passengers wish to register they will be required to look into a camera for 15 seconds, which records the unique pattern of their iris. Then this is referenced against their passport details in a database. On future occasions frequent travellers, for whom this service is aimed at, need only to look into the scanner and can pass through without showing their passport. Saving them time, but with obvious security advantages.
Nobody come up with a good reason for airside access for non-passengers yet?
