I remember an excellent lecture at the Southampton UAS in about 1988 from a man from the AAIB who told stories of how a number of F-4s were catapulted off carriers in the 1970s with their wings still folded. I think he said something like 12 were launched of which 6 crashed straight away with the loss of the crews and of the other 6, 4 of them had the crews bang out and the other two landed them.
My memory might be fading, but I think that that was right.
There were also some incidents over here with RAF owned ones - something like the wings being down but not locked and the locking indicators being missed on 2 x walkrounds and not seen by the lineys either.
The SUU always looked like one hell of a bling-bling accessory.
