Yup,
There was a recent TV programme about a English freefall guy who had a special winged jumpsuit to enable him to fly down horizontally to lengthen his freefall time. It mentioned Colonel Kittinger and had video footage.
Our guy had big big problems with the cold even at 50,000 feet. With that and the speed etc it could be a rough ride.
He was 'tutored' by another mad Frenchman who unfortunately didn't survive one of their earlier test flights. Fascinating programme, Something in the water over there I reckon!.
