At around 11;50 this morning [8th Sept] a Wokka passed overhead on it's way, presumably, into Odiham. They pass over us nearly every day [thanks boys, we like the noise].
This time it sounded So different. Almost like one blade had a whip tied to the end. A distinct high frequency swishing sound. Never heard that before. Am I being silly or is that because [a] there is a new blade fitted, [b] something is delaminating? [c] I am getting old and paranoid?
or [d] atmos conditions/vortex generation.... 72% humidity today.
Wokka fan along with SWMBO. Love it when I see them fast and low just off the A 303.
