So if Mexico, Guatemala, Beliez(?) Peru and other countires with monolithic sites join China -we'll know its a given that multiple ancient tech' is being 'turned on'.

Multiple sites does not automatically mean one group of ETs is behind it. Indeed it may signify that others are all in the 'race' to defend or win or guide to the end game - the prize.

I am wondering if all these 'missions' were to ancient tech sites, including those beneath the seas.

As for the OZ mission, I am not aware of any large man made structures, but we sure as hell have some of the largest single rocks on the planet such as Uluru and Kata Tjuta. Something embedded?

We speculated that these structures may be vibrating.

I THINK THIS IS ALL ABOUT VIBRATION.

The planes falling from the sky I think, has to do with this too, as a modern jet engine produces a very high frequency. Hans, you might shed light on this? These aircraft are built to compensate for these harmonic frequencies. People do get effected by the harmonics, in the form of deep vein thrombosis, and more common 'jet lag'.

The engines may be thrown off balance by anti-wave formations that casue catastrophic break down in the motors. Something like that happened to Qantas the other day. In fact its been a crap month for them..
