BJCC, I think you are probably right;
The time has gone now where you give someone a 'second chance', allow them to 'dry out' and then allow them back at the front end, no matter what the percentage of 're-offending' probability is.
Evidence and statistics of re-offenders in drink drive cases will prove that some of the offenders will most definitely offend again and that is not an acceptable situation when it comes to flying airplanes.
Sorry to say, but it should now be 'one strike, and you're out'.
It doesn't matter a damn that we all did it many years ago; that was then and here we are now. Times, attitudes and perceptions have long since changed.
All sympathies to those that find it difficult to meet the current regulations, but there again go find yourselves another livelihood.
We can still sympathise with those that may have a problem, but they cannoot again occupy a seat at the front.
