Ian Penrose contact details
I'm trying to contact Ian Penrose, son of Harald Penrose, a British test pilot who wrote several aviation books, including 'No Echo In The Sky'. I have a copy of this book and I'd like to digitise it for free access to readers. I'm assuming that Ian owns the copyrights to his father's books but have been unable to trace him to get his permission. The Royal Aeronautical Society at Boscombe Down have not responded to my enquiries.
If anyone can help in contacting Ian please let me know, either by post here or PM.
Thanks for info.
