Well, Haraka, I was awarded my 'budgie wings' in July 1972 and wore them on my uniform, flying suits and cold weather jacket until I left ULAS for RAFC in autumn '73. Including for the university degree ceremony where I was parade commander of our unruly mob in front of HM the Queen Mum.
The occasional chap turned up at RAFC still wearing his 'budgie wings' as no-one had told him not to. But they came off that evening.
