D120A - well there's one of your skills I did not know about! Reminds me of a n exchange visit to the Norwegian Air Force Academy in 1984 with 3 recently graduated students. Four of us Brits, 4 Norwegians go into a bar and about 30 seconds later a very bright an personable former student rushes back to the group "Over here , Boss, I have found 8 student nurses". and a pleasant evening was had by all (Thanks L K)
