| "Big Sky Theory" https://en.wikipedia.org/wiki/Big_sky_theory >In aviation, the Big Sky Theory is that two randomly flying bodies are very unlikely to collide, as the three-dimensional space is so large relative to the bodies. Some aviation safety rules involving altimetry and navigation standards are based on this concept. It does not apply when aircraft are flying along specific narrow routes, such as an airport traffic pattern or jet airway. >The Big Sky Theory has been mathematically modeled, using a gas law approach. This implies that collisions of aircraft in free flight should be extremely rare in en-route airspace, whereas operational errors such as violations of formal separation standards should be relatively common. Three critical parameters are the number of flying objects per unit volume, their speed, and their size. Larger, faster objects, flying in a traffic-rich environment are more collision-prone. http://code7700.com/big_sky_theory.htm >It seems that there are a lot of pilots out there that believe in the "Big Sky Technique." They think the amount of airspace out there is so wide and vast, and that they are so small, that the chances of hitting another aircraft is too small to worry about. And yet history begs to differ. The Big Sky - Kate Bush https://www.youtube.com/watch?v=sV7w5TaYjRA&ab_channel=KateB... They look down
At the ground
Missing
But I never go in now
I'm looking at the big sky
I'm looking at the big sky now
I'm looking at the big sky
You never understood me
You never really tried
Big Sky - Lou Reedhttps://www.youtube.com/watch?v=Ug_Z-gu7u44&ab_channel=Naoyo... Big sky, big sky holding up the sun
Big sky, big sky holding up the moon
Big sky holding down the sea
But it can't hold us down anymore
Big sky holding up the stars
Big sky holding Venus and Mars
Big sky catch you in a jar
But it can't hold us down anymore
Big sky, big enormous place
Big wind blow all over the place
Big storm wrecking havoc and waste
But it can't hold us down anymore
