I recall that all officers had to wear black armbands for a specified period, and that as there were insufficient held in stores, we had to provide our own. My then girlfriend scrounged an old black satin underskirt from her mum and made me one on the sewing machine. Got a few comments as it wasn't crepe, but it did the job.
Watched the funeral on TV at my parents' house in my pyjamas and dressing gown (without black armband!). The moment when one of the guardsmen carrying the coffin staggered as they mounted the steps to St Pauls sticks in the mind. Could have been disastrous.
Sixteen Lightnings as I recall. Could we stick 16 FJs in the air now? I somehow doubt it.
