This is way more fun than just "upside-down" — it's all different orientations! More seriously, it looks like an excellent testing and optimization program that cannot be done as well in simulation (and in any case would be needed to validate simulations). There's always something that pops up in reality that had not (yet) been accounted for in the simulation, and when that much is on the line, this kind of testing is critical. Great to see a glimpse into how it's done!
