It looks to me to be a vastly inflated event from the media. The Gazelle is clearly trying to land on the only suitable piece of level ground; without the aid of a sky shout how does the pilot communicate that the bystanders are sat in his only suitable landing site. Somebody clearly comes out and explains that the aircraft is trying to land and then having been educated they move away.
The alternative is to divert at great cost or wait until they get the hint; for how long?
