Accident
It had been an accident but Ward was now missing and Coulson along with Skye were injured.
She didn't mean to lose control of the plane and allow the rebels to open one of the doors, which meant that Ward was missing.
"I'm meant to be 'the cavalry', I shouldn't have lost that fight," May muttered in self-annoyance and hatred.
Five hours later the plane landed in the S.H.I.E.L.D airport, as the backdoor opened everyone was relieved to see Ward standing waiting for them to arrive.
He was covered in bruises, but he smiled.
"It was an accident," he stated.
