it appears that there is nothing wrong with wearing the wings which are effectively either a talisman or a brooch.
Is that what Ms Curtis-Taylor is saying? Personally, I don't think that saying the wings are a "talisman or a brooch" will run as an excuse. She is wearing them on a flight suit in the position they would be worn by a genuine RAF pilot.
As you were kind enough to offer to ask her: is there any news from her about the other two questions?
