I've seen the same video everyone else has seen and my opinion is no better than anyone elses. Departing to the south, as Steingar mentioned, there are no reasonable options for an off-airport landing.
My SWAG is a possible engine-failure event at roughly 400 feet AGL while departing RWY 21R. A puff of smoke may be visible about 13 seconds after rotation. At about 16 seconds, the pilot reacted. Feel free to ignore my conjecture.
[Update: ADSBExchange shows his altitude at 75 AGL. I would have expected more than that, but my previously mentioned estimate of 400 AGL is wrong. Even with a 700fpm climb rate, he would have still only been around 200 feet. At this point I suspect he was still generating partial power.]
The pilot initiated a turnback, to the left. Due to the low altitude, I doubt the pilot could have completed 240° worth of required turns (to make it back to a runway) in the best circumstances. As it was, he appears to have turned roughly 200 degrees before contacting the surface without attaining a wings level attitude, just short of RWY 21L. The turn appeared to be adequately steep to minimize turn radius and time in turn. But that is pure speculation based on the available video and my familiarity with the area. There is a lot of flat area around the runway, albeit covered with signs, taxiways, and crossing runways. An earlier rollout to level, short of the runway, MAY have been a better option. In any case, the pilot should be commended for quick action and maintaining control "all the way to crash" as Hoover said. These things all too frequently end with an accelerated stall and incipient spin followed by a smoking hole. Based on the circumstances I think the pilot did a great job.
