Conversely, if you really want to be noticed - perhaps, say, by the participants in a Mount Pleasant dining-in night who've 'forgotten' to invite anyone from 78 - descend at 4-600fpm/ 100kt aiming at a point just short of the target then pull up into a 30deg bank climbing turn approx 400m short so that you don't overfly any buildings. Lifts the cutlery off the table, apparently.
A certain Austrailian, DW upon the first time we took the OCU Chinooks to Upavon on detachment, he came up the valley at the bottom of the airfield at low level and bar seeing the odd rotor blade peaking over the field, nothing but a dull thud, then he then did just that, did a banked climbing turn by the bighouse to announce our arrival. It didn't go down well
