@ Trim Stab; There are certain fishermen who use goggles to dive for fish or crustaceans. Could have been some of those guys.
Very depressing though that in 2022, we are still seeing such apparently basic accidents happening to aircraft. Given the ever increasing global flying experience, CRM etc., and the long list of tests and hurdles one has to jump through - on top of one's flying licence - it seems very odd to me.
