If you know where I can find it I'll go and ask the permission for it
I have sent him a message on Facebook regarding it, I'm not sure if there is anywhere to download it or if you do need permission, there is a pepperspray script by him also. I know where to find the pepperspray script, it's on his website if you want the website link then I can link it for you
Update - He has replied saying (these were the exact words): "The speed script is just a minor add on to the move script, but I'm not by my computer at the moment though to send it". I sent him a PM on FB to the 'CPH Airport Modification', he replied immediately and you could also PM him on here, hope this helps
