After shooting, students make emotional return

MIAMI - Students and teachers returned on Sunday to a Florida school for the first time since 17 people were shot dead there, consoling each other even as they called for swift action to address gun violence.

"Imagine (being) in a plane crash and then having to get on the same plane every day and fly somewhere else - it's never going to be the same," David Hogg, a survivor of the Feb 14 shooting at a Parkland, Florida high school, told ABC television's This Week.

The school held a voluntary "orientation" on Sunday, with teachers and staff due back starting on Monday and classes resuming on Wednesday - a prospect described as "daunting" and "scary", but which is also a step for survivors to move forward after the attack.
