The comments re being able (or not able) to see the plane burning from the oil rig, you are assuming he saw it at point of impact re the satellite photos. As he described it, it was still flying, though moving towards or away form him. We just don't know how long it may have remained in the air after this time.
I am not saying I buy into the credibility of the photos, we need more information, but don't discount things just because the oil rig is too far away from the purported crash site. He never claimed to see it crash from memory.
