Three sets of sisters lost loved ones when Flight 3407 crashed in Clarence Center nearly 10 years ago. 

From their pain and grief, they've developed a sisterhood among themselves, supporting each other through get-togethers, sharing birthdays, vacations and retreats. 

It's not something they expected to happen after a heartbreaking loss, but it's a bond that has helped sustain and carry them forward. 

In the second half of a two-part series, Casey Bortnick talks with the women about how they've become a tight-knit group.
