Not sure if the mech-walker suit is inspird by Iron Man's Hulkbuster armour, but there definitely seems to a resemblance. I can see it now; Thunderbirds Are Go: Age of Ultron, lol.
Out of all the Tracy Brothers, Scott & Virgil are the two that seem to be the closest as even in the original series they were the ones watching their backs the most. that's not to say they valued their other siblings less, but they just seemed closer than the rest.
And from the coming soon clip where Virgil is trying to put his foot down insisting he will bail his brother out from the radiated mine is just a testament to that bond.
Thunderbird 2's landing sequence is pretty much similar to it's original counterpart but the addition of the rotating VTOL thrusters is a nice touch Virgil can gently adjust it's landing sequence and tilt the thrusters as to where applicable whereas you if you look at the original variation the thrusters were pretty much in a stationery position and had no means of being rotated.
I like how Razmus was able to make Scott sound really in despair and scramble away from the Iron Man mech suit 44. lol. As that just shows the range he is able to project without into his Alan Tracy voice which is a lot squeakier than Scott's.
I look forward to this for Saturday.
