People like you two made Abrams look like a barn

Grin... I loved my roomy Cadillac of a tank!

RU went a different direction - specifying that only short guys could be tankers.  Such a sad, discriminatory policy. Just mean spirited.

AFAIK fighter cockpits and space capsules (at least the early ones) are sized for shorter pilots/crew, since bigger means more mass, and so on. Good for me (5’7), but bad for you. But hey, you can get stuff off the top shelf, and have a much better chance at being in the NBA, and all the other advantages of height. So let us shorter people enjoy what perks we can get…. 

But yeah, the world isn’t really built for the very tall people…

 

LAWLZ!  I'd forgotten about that scene!  So true! 

Oddly - I have a friend who is both taller than me and an Air Force officer.  He's a pilot. 

But. 

Like you wrote - all the fast movers are for the short guys (Fighter designers are mean spirited little people - just like Russian tank designers). 

But refueling jets?  Yeah, sasquatches can squeeze into the seats!

A video about Wang Yaping doing the underwater training for preparing the CSS's EVA mission. You can see the  Feitian (飞天, Flying in the Sky) Spacesuit after improvements.

Seems like CNSA now can put the Orlan suit aside which bought from Russia before

The total value of the xEVAS contracts is $3.5 billion through 2034, a figure that assumes all task orders are exercised. NASA officials at the briefing declined to break out that total between the two companies, stating that information will instead be in the source selection statement for the procurement, expected to be released publicly in late June. In many other commercial procurements, NASA has released the value of individual awards to companies.

bring a tank to the moon

What about the dog? Why would you on Earth bring a dog on the Moon? That's crazy.

No, the True SuitTM is the Kerbal one.

Grumman Corp. spacesuit for NASA

The design makes me wonder: there is no air pressure on the Moon to keep it open, and the suit arms are obviously too short to help with a pot.

Why need the purposed  wide hole???

Now that thing is nightmare fuel. Why the oversize torso, It only makes sense with an rear hatch like the spacesuit in Freefall

This is less a suit and more a small pod with arm and leg waldos.  Not sure if you can pull your legs into the pod, but clearly you can pull your arms into the pod for operating controls or the like.

Given that you only need breathable atmosphere in the helmet, what is the minimum pressure needed in the body of the suit? 

A combination of mechanical counterpressure in the limbs and scalloped joints could make for a functional vacuum suit for use in an unpressurized part of a ship and be smaller and more nimble /less exhausting for the wearer.  Maybe combine this with an oversuit for a true spacewalk?  The oversuit then only really needs to provide the

You need pressure on the chest or you won't be able to exhale properly.

A while ago I asked a doctor about ventilators and leaned that about 0.03 bar of overpressure is typical. Breathing pure oxygen you need at least 0.18 bar. Given that the pressure on Mars is only 0.0061 we still need around 0.15 bar of pressure applied to the chest
