this can be done in a private match with just 3 people.just make sure when the host creates the match in the settings they set it to include bots to no and set the game to one round,single flyout.who ever is going for the achievement hit the y button to select a team either axis or allies,once they have selected the other 2 people select the opposite team by hitting the y button.once the match starts the team of 2 will take off and nose dive into the ground which fails the mission and unlocks the achievement for the player on their own.
if you include bots its classed as even teams so make sure include bots is set to no .doing it this way makes it literally a 30 second achievement
it will also unlock if you dont already have it the
