failure to hover taxi

[ssangyongs]

i watched this video onyoutube, about this R44 trying to take off immediately in an open space...they said its pilots failure. But what if we need to clear obstacles in a confined areas (e.g. in the middle of a jungle)

how to avoid things like this from happening
