Yeah, they were testing a plane flown completely by a computer. No one was on board (thankfully).
Found the other videos while I was looking for this one:

It's a video of the Russian Sukhoi-30 combat jet that crashed at the Paris airshow in 1999. It nosedived, and then pulled out at the last minute, actually
scraping the ground, and then pulling back up. Both pilots ejected at the last second before it exploded and were okay. Some of the photographers were only 100 yards away.
