Crowdsurfing doomfist? and looking for advice

So I unlocked his airstrike achievement last night and saved the clip. The only thing is I have no clue how I maintained air time long enough to get max damage. I was looking for any of you guys to have a look and let me know what you think.. also any tips for landing that 6 man meteor.
