you can't substantiate it.
Similarly FGD you have not as yet substantiated your claim as to why the GT authored "book" titled Qantas Flightpaths moved you to such an extent that it gave you "an enormous respect for the man." In that book there are some extraordinary claims about the way Jetstar Asia was going to have an enormous upside for Qantas! Clearly his ability to forecast the future was not what generated that respect?
