Frankly, it never ceases to amaze me how people can be so bloody stupid - yes, sometimes you get caught out by the weather, yes there are pressures to get the job done, yes we are human and make mistakes - BUT, that flight at low level in an obstruction rich environment in such poor weather was STUPID - plain and simple.
If you go down then slow down - I have hovertaxied in cloud and fog to get a job done and gone under and over wires - it can be done safely if you do it slowly and know when to say NO.
