Is it me, or is it my age lately
The issue here is: AGE DISCRIMINATION,
nothing more and nothing less.
This diversion about whether one is fit or not is accepted as a compulsory requirement and has never been an issue.
Skills shortage / moving over for younger ones - never heard that before
The poll on the government web site and most other actions being carried out are about winning the case on the subject of age discrimination. The discrimination being that if one flies a multi crew a/c one can fly for an additional 5 years because of their age, that's all.
The other issues are interesting and in themselves may have kudos but don't get side tracked on this one.
