Strikes me as pretty damned stupid and arrogant, approved or not, passengers or not - a little bit of turbulence off a hangar or a bird down an engine and you have no height or time to correct a resulting flight path variation. Airliners are too big and have too little agility/responsiveness to be doing that sort of flypast. A few hundred feet is one thing, but a few tens of feet is another - it looks clever, but anyone with a small amount of wit knows how stupid it is. It's the same as boy racers in their hot hatches and on their bikes.
