Well, with my 'armchair quarterback' baseball hat firmly put backwards on my head, and armed with Green-dot's post, I feel pretty sure that I can guess what 'happened', and I would say on that basis there are lessons to be learned by Corendon and the crew, and the only thing hurt, fortunately, was pride, company image and budget.
As they say "Not a single Corendon passenger was harmed in the making of this production".
No, I'm not going to 'publish' my 'findings'.
I suspect most 'professionals' could guess too.
