Should I be worried that a group of people are depicted standing in front of a jet engine, that appears to be blowing their hair *backwards*?

Being pedantic, one could point out that the fan was turning too slowly to create much of a breeze anyway, so an ambient wind could cause the hair movement. Having said that, I've noticed that high-bypass-ratio turbo fans windmill backwards if there's enough wind from astern. Against that, the sound effect was that of an engine winding up, so it could be suggested that the engine was just starting, hence just spinning the fan forwards. The final argument must surely be that the breeze was supposed to be associated with the engine though, so overall: it's bollocks.

Err, I was referring to an unpowered engine. And thrust reverser doors are usually pretty obvious when they're active.
Well I'm certainly no expert, but some blurb on high-bpyass turbo fan engines suggested that they achieved the trick more discretely using doors in the bypass ducts. Is it possible to tell what type of engine it actually is from that footage anyway? Still this is UKRM so it would be a shame to let the matter pass without a bit of uninformed (certainly in my case) argument wouldn't it? -- +-------------------------------------------------------------------+ | Pete Fisher at Home: | | Aprilia Shiver Yamaha WR250Z/Supermoto "Old Gimmer's Hillclimber" | | Gilera GFR * 2 Moto Morini 2C/375 Morini 350 "Forgotten Error" | +-------------------------------------------------------------------+
Yes, AIUI newer engines don't use those bloody great barn doors out the back. Eg as depicted here: http://en.wikipedia.org/wiki/File:Air_Canada_777.jpg heh
Being a tad more pedantic one could ask if .. "Well, as it's only a fucking advert, is the engine turning and their hair blowing even meant to be connected?" Maybe not, they might just have had their heads in the clouds ...
It's quite simple, really. It's an advert. The producer says, we need to show air blowing and the people looking at the engine, but make the wind blow their hair back, 'cause blowing it forward makes their hair look ugly. The people were shot on a soundstage, the engine is an animation added later. The producer doesn't GAF about reality.

There's just a light breeze blowing from behind the engine, turning the fan slowly and ruffling their hair. It's also turning the wind turbines in the background. BTW, did you notice the flying whale at the beginning. Do they really do that?
