I was watching the following video, showing a 757 landing on Skiathos, Greece.

If you take a look at the 8:26 mark, you'll clearly see that all jet blast fences are positioned with their support toward the apron.

Can someone who knows better than I do confirm for me that this is the wrong way to position jet blast fences?

Here's an image, for those who can't/won't watch the video: enter image description here

They're being used in a different way than normal in that case. That's just a taxiway, not an engine run-up pad, so they aren't there to deflect max thrust jet blast. They've been arrayed "backwards" to kind of trap debris that gets blown toward the building as aircraft taxi by. That's my guess anyway.

    $\begingroup$ I'd have to agree with u/John K here, since its only a taxi way they don't want debris blown into the building. Imagine a small rock gets blown while a plane is moving it hits the fences and is directed at the ground, if they were angled towards the building it would act as a ramp and ricochet it right into the windows. $\endgroup$ – Alex Dec 13 '18 at 14:51
