Fair enough; is drug testing an issue in the EU then?
If the EU objects to it, that is tantamount to enabling drunk/drugged workers to perform maintenance on US registered passenger jets, which looks pretty bad form for the EU to be defending
Next time you take a flight on say Continental Airlines, the aircraft may have been maintained by some EU based Repair Station whose employees have been protected from drug testing by EU law.
Does the EU really want that? It would make the evening news.
