now is the plane going to hit me or is it going to catch on fire or blow up. reporter: pieces of the plane rained down on bystanders, but no one else on the ground or train was hurt. it s a story that has garnered international attention and praise for a group of officers who went beyond the call. risking their own lives to save another. many now calling them heroes. what goes through your mind when you hear that? you know, honestly that s not the word that, you know, we associate ourselves with. it s part of the job. officers around the rorld do this every day. maybe not a train coming at them, but they re saving lives all the time, putting their lives on the line. he s out. he s alive. reporter: josh campbell, cnn, los angeles. hello again everyone, thank you so much for joining me this sunday, i m fredricka whitfield. we begin this hour with the crisis in ukraine. president biden just a short
