Despective ?
No, I'm just don't think most people let military aircraft showcase above crowded area (you remember that russian jet crashing in the crowd don't you ?)
I +1 this !
I'm workin with datacenter and there is 1 unit that is the most laughable in all :
BTU/hr (British Termal Unit) which is the heat absorbed by a cooling system for example
1 BTU is the amount of work (heat) needed to raise the temperature of one cubic foot of water (eq 1 pound of water) of 1 °F
-> not a sigle metric unit in that so totally not understandable for 99% of the world population :D
Knots and nautical miles are much more "logical" than mph (1 nm is the lenght of 1 minute of arc (1/60 of degree) in longitude - so it is 21600 nm to go all around earth at the equator (360° so 360x60 minutes, so 21600 nm).
Do you play with another language than english ?
If there is another folder under DCS World>mods>aircraft>A10C>Missions> (I've got FR... but depends on where you're from)
Put the missions/campaigns in the right folder and voila !
