A FAA chap I once knew had an engine failure in his single engined jet over central London.
At night.
Somehow he got his Attacker down at some aerodrome nearby. Of course we had more of those back then, as well.
This bolleaux of not allowing the Harrier, admittedly with a glide ratio only marginally better than that of well-thown manhole cover,
must stop. Tell the H&S pratts
to do one.
"So, meine Herren, tomorrow ve vill attack ze London docks at low level. It is strengsten verboten for ze Tommies to fly das Spitfeuer over Central London if to glide clear they cannot......."
Fortunately they didn't seem to worry about such things back then - as Sep 15th 1940 was to prove.
