Someone out there will know for sure but I think a breath test on the ramp has been a possibility in Helsinki for a long time? Part of the local law, I understood.
TeeTotal for pilots is complete nonsense, if pilots, of all people, cannot show greater self control than average then there is no hope, IMHO. So if TeeTotal were the case then presumably we can expect it to apply right across the spectrum of people who have responsibility for other people's lives and well being?
Pilots, Cabin Crew, Doctors, Nurses, Lawyers, Train Drivers, Bus Drivers etc. etc. The list is endless.
