It's still a lot of work and people doing any testing expect to be paid.

There's the time-scale like I said, how long would it take for all those "qualifying" to be tested?

You might as well say that everyone qualifying should have a full medical which would entail a complete eye test, an echocardiogram, an electrocardiogram, a chest X-Ray and a body scan. Throw in a blood test for diabetes, kidney and liver function and blood oxygen level?

When that's done and if they pass that, next is an IQ test followed by a theoretical test. Then and only then would there be a practical test. Where would the line be drawn if the above were not done???
