I made this for my own use, because when I use the ace dossiers to check out the HAs of the squadrons in my vicinity, I prefer not to know the date of their eventual death.
There's a separate set of "cut down" biographies for each year (e.g. the bios to be used in 1916 end in December 1915). Apart from that, I have neither rewritten nor expanded upon the vanilla biographies.
This version presents its own drawbacks (late in the year, the information provided will be several months out of date), but if your main concern ist to not be spoiled on the death dates of the aces, you might want to give this a try (backup of the original files is included).

Made with V 1.26, but should work with V 2.XX.

Ah! Very nice.

Hmm, I wonder whether the biographies could be set up to autocomplete over time like the lists of aerial victories...
