Stanwell,
Your mention of TCT's Wiki page prompted me to have a look at the edits of this page. To do so, click on the 'View history' tab at the top right. This opens this page:
https://en.wikipedia.org/w/index.php...action=history
which contains some interesting information.
The page was started by MurielMary in NZ on 9 January 2016. There have been mutiple edits since then, including several by JaySata, but any edits referring to flights being "not solo" have been systematically removed, as has any reference to the Goodwood Stearman/Robinson "interfacing". Some of the edits come from an IP address that is in Goole, and another in Chang Mai in Thailand!
It is interesting that there is no mention in the text of the US flights, that ended with the crash at Winslow. although it is referred to in Reference 13.
