We seem to have arrived at a point where pilots can not only loose their jobs but also spend time "inside", while not having the means to assess their fitness to fly.
At the present time I could enjoy a shared bottle of wine with my wife in the evening then more than 8 hrs later find my self over the 0.004 limit.
Has the time now come for either pilots to become teetotal, or to carry a proper calibrated breathalyser as part of their equipment and test themselves prior to leaving home or hotel?
