I've recently had an idea for a Red Dwarf (Not sure if any of you might have heard of it) fanfiction entitled 'Back To The Past', where they are flung back into the past on Earth by a Time Hole, and they work their way through the past, trying not to alter anything because of causality, and it turns out they actually caused all of these events. (Slightly influenced by Blackadder Back and Forth, but it's not, I assure you...)
I've got a few things I could mess about with, but I need some more that were triggered by luck:

Dinosaurs wipeout
Henry VIII and his six wives
Titanic
Great Fire of London

Need some more. Sorry...I don't really know too much history, so some ideas for things they could mess about with would be cool.

Phobos

Hindenburg disaster and the Boer War.

Drzava

Drzava killing himself due to all that English crap being on the high school curriculum and a cure for AIDS never being found as a result

teflon

With its year-by-year cross-referencing, I think Wikipedia is a one-stop source for this situation.
