Updating this for the modern era, I suggest the Airbus 380. Crash a fully fueled pair going full speed at about 800 feet up, with the crowd back 2000 feet.
I think they got the crash sound from the onboard camera equipment, and the engine sounds from outside cameras. Then mixed it together with tense music for dramatic effect.
NASA did something similar back in the 80's, with somewhat more spectacular results.
I guess the pinnacle for an advanced civilization would be crashing black holes into each other.
There goes my morning. I will be thinking about this for awhile...
I keep on thinking on how can we do it even with Super powers..
It's a bit hard to see what's going on with the Black Holes though. A better show would be to crash two near-collapse stars together to trigger a supernova. As an added bonus you get a fresh supply of heavy elements, which your civilization might be running low on since your have the capability to fly stars around.
Maybe that's what LIGO is detecting now...
Why not just use one of the 737 MAX planes? They're gonna crash anyway, might as well use them for entertainment.
The 737 MAX seems like a better bet. Nobody would ever fly on them again anyway - and they crash themselves!
