Do you have a better explanation (more likely, credible, and with some evidence) for the helicopters than avoiding kicking up dust on the long, winding road up the mountain that would give the CP offenders time to delete files?

I would really be interested in a hypothesis that had some substance to it.

It will be interesting to see how long it take us to get the truth about the shut down of this observatory. It's pretty obvious that the official story is nonsense.
