Spacex blows through the limits of physics

 Humanity has always been limited by physics, but no more!  The biggest limit was the strength of materials.  The Bronze Age was destroyed by the Iron Age.

You would think we'd be limited by the strength of concrete, but not anymore.  We can launch with concrete debris and iron rod all over the place.  Would that knock out an engine or two?  Perhaps nothing was learned by the explosion in the air - one bonky engine would shake the whole thing apart.

But concrete is such dull engineering.  Perhaps, like nuclear plants, they contracted all that out.  It has nothing to do with shiny rockets.  

ps -- Twas concrete that killed the Big Beast.

pps - This is dieselgate all over again.  Imagine an engineer, and a snorting MuskyTusky comes charging at you "Make this pig fly!"  You might stutter something like 'physics', but in the end you'll say 'Yes, sir' and prepare your resume, while designing something you know is cheating.
