Giganta is back!!

Does anybody here remember ~~Vera Lynn~~ Giganta?
Remember how she said that
We would meet again some sunny day

Some year ago, I was checking how big a space plane can be when using TweakScale and KJR/Next, and made Giganta.

And she flew - boy, how she flew. And what magnificent... cargo bay 😇... she have! I essentially shoved a whole Space Station in orbit on a single flight.

But volume is one thing, mass is another - I remember wanting kicking into the skies some serious weight, and did some iterations more.

Well, this week I found that savegame by accident, and found one Giganta forgot in orbit with some poor Kerbals stranded there since the last time I fired up that savegame.

So, let's rescue Giganta with another Giganta! What could possible go wrong?
