The twists and twirls this thread is continually taking make it as compulsive daily reading as Radio 4's programme The Archers is for listeners.
I am sure that Boeing and Artemis Investments didn't agree to bankroll this whole programme on a hand shake after a few presentations and cozy lunches, there would have been lengthy and detailed sponsorship agreements, no doubt crafted by Tim Kelly, the
PR man who describes himself as a sporting sponsorship consultant on his company website and Linkedin page.
If TCT and her team really wanted to show their original intention was a solo flying expedition with en-route "outreach" activity why don't they publish their original proposals to potential sponsors (which probably went to more companies than just Boeing and Artemis) suitably redacted to hide the estimated costs and commercial aspects of the venture?
