I take this to be about war, and the governments not telling their citizens what's going on.

Birds go flying at the speed of sound - Bombers and other fighting planes going so fast.

Birds came flying from the underground - Nukes coming from underground bunkers.

All that noise, all that sound - Explosions, gunfire, etc.

All those places that I have found - They're being destroyed.

How long am I gonna can stand with my head stuck under the sand - Ignoring what's going on in the world, not being told what's going on at least.

Ideas that you'll never find or the inventors could never design - Everything that can be cut off by war, or maybe the just incomprehensible idea that people would hurt each other.

The buildings that you put up - The institutions, systems, etc, being destroyed.

All lit up - Obvious explosives imagery.

All those signs I knew what they meant - We can all see war and such coming, just by what's going on in the world.

yeah.. a fantastic explanation

@StellaSymphony old post I know..... just read today that rusia tested december 2018 a nuklear misle that goes 27x the speed of sound and boasted it therefore cannot be detected.

I tend to think of birds flying at the speed of sound, is how it all began with the Wright Bros. using the flight of birds as inspiration to invent airplanes, and much of scientific endeavor mushroomed from then on.... quantifying(analysing and measuring and copying) the speed of sound, light, planetary motion, etc....in such a short timespan, when considering the time span humanity has existed on the earth.
