Very sorry to hear of Stephen’s passing, he will be a great loss to the Space Team and the wider CAA. Ever responsive, ever constructively challenging, and ever helpful, his dedication to his work was admirable, and his knowledge of his subject great. He will be very greatly missed, and leaves an enormous gap to fill. E-mails to OGC will not quite be the same again. May his memory be an inspiration to us all.

The UK Space Agency Policy Team have also asked me to pass along their condolences and their fondest memories.
