The Dana Air flight went down in Lagos Sunday, killing all 153 people on board.
We've learned that Josephine and Jennifer Onita were on the plane. They'd been in Nigeria for a wedding. Josephine graduated from the University of North Texas and Jennifer was a graduate of Texas Tech.
Right now, investigators are trying to determine what caused the plane to crash. Records show the jet involved in the crash suffered a bird strike two years ago and lost engine power.
