[TowerTalk] [MWA] OH8X 80-160 monster tower collapses

[Andre VanWyk]

Kelly,

This question had been dwelling in my mind since I heard what happened. For
a project of this magnitude and the engineering that went (or was supposed
to have gone in it??) into it, one would think they had access to endless
engineering resources as money was surely not an issue. Looking at the heavy
duty steel used, something does not add up when it comes to the design...

I too will be shredding my clothes and covering my face with ash and dust in
mourning of this tragedy. Does this mean I will now never get this entity
confirmed on 160m?

I offer my condolences to Radio Arcala, but I have a question about that
explanation: shouldn't the engineering of the tower system have accounted
for the possible failure of a windload-mitigation system?

Does anyone know: was it insured?
