For Alliance, you can jump down to the propeller of the airship and jump down right as the timer expires at the beginning to get down before anyone else, allowing you to get the azerite needed for the achievement "A Good Start", which requires you to gather 100,000 Azerite in Seething Shore.
You can also get other achievements like "Claim Jumper" and "Seething Shore Domination" which are components of the "Seething Shore All-Star" achievement, which grants the tile of "Prospector".
Jump down from where I am in the first picture on to the propeller.
Right Click your parachute buff in the top right to drop faster after the timer has expired
