No doubt it was, but at the end of the day NASA were the ones who blocked their man from giving a 23 minute presentation at a symposium on the subject at the last minute. It took all of the other scientists threatening to hold a 23 minute newsworthy silence, rather than change the agenda, to make NASA change their minds.
Back to the subject, though, I now think the popcorn vids are fake, simply because I know people who tried it out and got cold popcorn. YouTube can be just like Wikipedia I guess - completely unreliable unless there's a stack of sources and references listed.
