Megan Hoffman - a English Literature student from Pewamo is one of them. She's been looking forward to a trip to London for years.
When she saw the footage of the attacks the other day, she was at first worried for her friends who were already there. After she learned they were safe, she talked with her parents about whether or not she should cancel her trip. Everyone agreed - she should still go.
Megan sees the attacks as an isolated incident that could have happened in any big city. She says she feels safe going there, and plans on enjoying her six weeks in England's capital city.
She, and the other 139 students, fly out this weekend.
