Supporting evidence?
If it's real, there should be somebody clamoring for attention with his eyewitness account, a news report, a blog from another pilot in attendance, or some such corroborating evidence. In the absence of all of the above, the best explanation is that it is a CGI fake.
I know eyewitness accounts don't carry much weight in most quarters, most of the time, but of course, there are huge exceptions.
