Well, you could say the UFO was the other blade? (the bent one that was bent by the other one, the other one that was missing but was there all along after it fell off). But that parted company with the rest of the structure unexpectedly due to mechanical failure TBC why, (says the press release) and the noises heard have not been tied to the lights. I expect there is a bit of rethinking going on in an attempt to reschedule the event in their minds. Give it a few years and it will be lore.
