Concordia, -64-rescued- from-lifeboats/ 66633

Tall Ship Concordia sinks off the coast of Brazil, well trained crew made
the difference between tragedy and just a financial loss.

Never heard of a microburst sinking a vessel or even on the open sea but it
does make sense.
Wrong place at the wrong time.
