Sofiia Smovzh, Serhii Kolomiichuk and Dmytriy Omelyanov are 17-year-old high school students from Ukraine. They were participating in a national science fair in Kyiv on the morning that Russia began its assault on their country.

Kolomiichuk and Omelyanov are from Dnipro, in central Ukraine. On Feb. 24, as they heard explosions go off in Kyiv, they made the long journey home on a packed train.
