Hmm, dat good thick Greek shit with no added sugar.

I do not have one, I just eat a lot of yogurt which comes in square containers. Loads of other similar things come in the same kind of tub so I figured you would know what I meant.

While more of a DIY than BFL option, you should consider those square yogurt containers. They are food safe, seal well, and stack.

It is just a freestanding square fireplace-thing with probably baffles up top to create some warm airflow.

The Soviets were actually ahead in a few relevant areas, namely exotic metalurgy and certain aspects of aerudonamic refinement.

The Tu-144 was at least funny. Its 'Soviet engineering' nose solution is amazing.

It was also theoretically a lot faster, but shorter ranged.

It was also a testbed for many technologies which went into the Tu-160, the worlds fastest production strategic bomber.

The difference might be in longer flights. Paying twice as much to go twice as fast is not really worth it, except for a >16 hour flight, then it starts to seem worth it.
