Hi John
Thanks to the wonders of the digital World, I have found the article that led me to believe the procedure was developed for the Mirror Group operation. It makes quite interesting reading, if only for the dream of masses of rooftop helipads in central London. I now realise that the article doesn't claim this was the first use of helipad profiles (Worldwide) but you might see where my confusion started. Hopefully this link will work:
