I don't know how this twit, GT, can get away with publishing safety ratings for airlines based on not much more than opinion and who gives him upgrades and CL membership. GT has zero actual technical qualifications or licenses.
When comparing GT's safety ratings with those of two subscription sites used by large companies to determine airline and travel policy for thousands of employees, there are some significant and potentially dangerous differences.
My company's legal department is of the opinion that GT's disclaimers are invalid as the site offers the very advice (airline safety ratings potentially affecting a choice of airline based on an "assessment") from which it seeks to disclaim itself and that the user isn't required to "agree" to the disclaimer prior to using information from the site.
Consequently, GT may find himself in court one day, based on the ratings which are completely opposite to the sites used by professionals.
