Only thing I think is missing from the airdrop is the contact position is a bit rough. I have tried and I cant get anywhere near as close as you so I do know how hard it is but I know you can get there. Youre still making first "real" contact with the ground with your hips/leg and then rolling through the mill, to make it even cleaner/clowier you gotta be more inverted as you make that contact so your legs are more in the air, you roll on the shoulders/back rather than your hips/back. Super hard to perfect but you can hone it for sure.
