i was looking at this event chart - both the crash time and takeoff timed chart. there is a big wikipedia page on this here.

Lech Kaczy?ski the 4th president of poland who died in this accident has a birth chart on astrodatabank here: http://www.astro.com/astro-databank/Kaczynski,_Lech

it is an interesting piece of russia/poland relations that i was unaware of previously. now that the new-old cold war has started up again? around ukraine there are conspiracy theories on the cause of the plane crash.. i was reading about this today and don't personally believe in the conspiracy theories fwiw.
