Aurora1827 is the name I use everywhere, as I could never remember more than one username. Aurora Borealis are the northern lights - you may be able to guess approximately where I live......18270 was my registration number at university. Over here they post exam lists with numbers rather than names for confidentiality reasons, and after 4 years, that number is ingrained in your psyche....
In other words, nothing to do with helicopters.....
