Your Skipper hopes that he is not giving anything away, but NESers should please note the following when considering Investment decisions in TAT.
Turbo is a fine figure of a man, although as all NESers & trained pilots would know, his grip on the controls appear to be excessive, and you wouldn't want him to have that grip on yours.
What Turbo fails to inform is that his compressed coal also has a high percentage of compressed and dried cat poo, which raises the CV of the mixture to spectacular levels and does not require any fuel storage on the aircraft.
Tubb has developed steam which can overpower rotor downdraft, and this has other spectacular applications that are presently being patented. Stay tuned for more news.
