OK cool.
Well, I travel a lot, and live where I have a view of Heathrow inbounds, my office overlooks one of the runways at Heathrow, so the alerts I have set up are all the aircraft that I 'need' that are likely to visit Heathrow and are sent to my blackberry so i can leave the box running all day from home.
The 10,043 aircraft I loaded in were a combination of the remaining aricraft around the world that I 'need' and also a dump of the aircraft comming up for delivery that I will 'need' as taken from the Ascend, nee Airclaims Database
I did it this way rather than writting out and swapping the Smartview aircraft everytime I go away as it would be pain in the rear end :-)
