Another Vulcan-ism was the so-called 'reverse flap effect'. If you were low and pitched aggressively, the elevons (Mk 2 - or elevators on the Mk 1 and 1A) all deflected upwards reducing Cl and down you sank - if further pitch was applied things just got worse! Similarly, overflaring on landing caused sink, checking forward could cause definite ballooning. Somewhere there's a videoclip of the Tu-144 demonstrating both effects and smiting the ground somewhat firmly as a result.
And yes there most certainly was considerable PE effect on the altimeter on an Instrument Approach. I seem to remember having to add 100ft to declared values - using a DH of 300 ft indicated on a PAR or ILS.
Mr J W Phillip lost 3/4 of an acre of his crop of Brussels sprouts, not cabbages when XA897 blasted them flat at London Airport - assessed as being worth £75. Damage to the ditch was assessed as £10 12s 6d....always wondered how they managed such a precise assessment!
With acknowledgement to my first Vulcan captain, Andrew Brookes, for information gleaned from his excellent book 'Crash' - which cost me £16.95 some 10+ years ago! You can see Andy fairly often on TV giving his views as a Defence Expert from the Institute of Strategic Studies. Or as a wide-eyed youngster in a photo on the back of an old Buddy Holly album, eh Andy?
