Dead_Star_v2

Hello guys and girls I have a quick question Is it possible without using hacks or macros to fire whilst in mid jump in battlefield 2??? I have just watched a tutorial of a player showing players how to fire a sniper rifle whilst jumping. I have been playing Bf2 for over 2 years now and didnt think this possible. i have just been in an empty rackage server and followed his tutorial step by step yet i still can not fire whilst jumping. Thank you for your time Deadv2
