Who would want them, and for what purpose?
The commercial value of the images you're likely to make is very small, if it's there at all. A quick search on SS shows that of their 29 bona fide "red bull" shots, not a single one has made it to the 1000 most popular "airplane" images. At best, perhaps one or two of these 29 was purchased.
Unless you've got a particular shot in mind that addresses a unique market, it's a very safe bet that you'll be wasting your time by attempting to corral commercial stock imagery from this event.
