Hi Reheat On,
Thanks for your insights on managing sunlight during aeros - rather more complex considerations than in an airliner cockpit. (We used to use the Daily Telegraph on the Afrika Corps in my youth, if the stick-on meal-tray lining wasn't big enough).
I now realise that the sun would have been well under the port side at the top of the manoeuvre, so perhaps not a dazzle factor at that point? As you seem to imply, disorientation can affect any of us without warning, for example during sudden head movements.
That link to the Shoreham aerodrome chart doesn't work for me. The only paved runway dimension I could get before my original post was the runway length, so I assessed the width by measuring it on the satellite picture. Its proportions are not dissimilar from a 10,000-foot instrument runway. But I'm not suggesting that a runway is the only visual cue to height assessment, as Cows Getting Bigger might remind me.
