What is the Significant of 265,821 feet?

That appears to be the altitude to which DCS models the atmosphere. I use the WeatherMark script to get the data. All altitudes above that are exactly -459F (with zero wind and pressure obviously).

 

265,821' is -105F BTW, on a 40F Syrian day in January

 

Over 200K feet is pretty damn impressive!

 

I sometimes use DCS to simulate weather, without even any combat stuff going on.  It seems pretty realistic.

The ORIGINAL Karman line was agreed as being around 270000ft, maybe this has some significance?
Recent advocates state that the demarcation of space should begin at 50 miles, so it would fit if ED are going with it?
