On April 15, 2011, I was flying (as pax!) into ENGM in a 737 by a well known airline with white tails and blue print (not to mistake with blue tails and white print).
After landing I dared to ask the captain about the PMS. He looked at me as if he saw water burning and made an annoyed remark about the siteseeing tour over Norway that he didn't like. I did not tell him that I did like it and I did pay in advance ;-)
(He was directed to 19L on his request, he told me)
