The same reason that space vehicles and meteors burn the atmoshere when they encounter 'air' at high velocities.
The same thing that destroyed the space shuttle "Columbia"with damaged heat tiles on the wing edge when it re-entered.
I have wondered that same thing from the beginning.
I was thinking they would only be used more along 'line of sight' ranges.
"Line of sight' very loosely defined here! It would still have high velocity at ranges that are occluded by the 'over the horizon' ranges.
Maybe more accurate to call it 'follows Earth's Curvature', or something.
It would be useful info to know what the projectile's velocity is at the stated 100 mile range, to enable calculations for remaing energy.
I know from long range target shooting that projectiles slow down fast.
With a 100 yard 'sight in', that same bullet is striking the target about 10 feet below point of aim at around that 1000 yards, and a 10 mile per hour crosswind will deflect it around 2 feet, IIRC.(fuzzy on that memory)
The flames/fireball are similar to the the effects of say, a meteor entering Earth's atmoshere at high velocity...no fuel involved.
No trick here, just super heated air and plasma caused by friction, and maybe some 'fuel' from ablation of sabot and possibly projectile.
Similar principals enable deisel engines to combust fuel without a spark plug...compression causes friction, friction causes heat,
I call BS. We are talking FOSS here so there can be absolutely no security issue because it was produced by a large community of do-gooders who vetted all commits for us and this means that every bug gets caught within seconds of being committed.
It is a fact (not theory or guess) that only commercial, closed software has security flaws.
Well, it is a security flaw/hole until it's been plugged.
I was going to mod you up as I once had to study COBOL for exams, a long time a go. But then I clicked on your hidden replies and my, oh my. I had to reply instead to say that you really have attracted one of the most virulent trolls that I've ever seen on slashdot. You should get some kind of flair next to your username or something.
There were thousands of independent ISPs once, they extincted themselves because they lacked the vision to work together and instead died one by one. I had a ringside seat.
They went extinct because the cost of building the infrastructure to provide the broadband internet access that consumers now demanded. It fell on king telecom to build that out. Even with the number of ISPs that you pull out of the air, I doubt they could collectively come up with the 100s of millions necessary to make this happen. Government helped the big boys make it happen and also created regulatory nightmares to ensure that the telecom industry is an oligarchy.
