I did once see a real RN aircraft carrier in Oslo harbour - I think it was HMS Victorious or HMS Ark Royal in late summer 1961, but as I was rather young at the time, I'm far from certain.
VERY impressive though - and, err, somewhat bigger than the Invincible!
Nice sea state, Tudor - and excellent piccies!
HMS Victorious Proper Carrier
