I came across this on Adfreak and I have to say, it's a lovely way to take something that everyone pretty much ignores (the inflight safety video) and ad a twist. It's charming, still informative and it made me smile.
it also proves that you can and should be showcasing your brand voice even through mundane channels. It helps to differentiate at all levels.
