It is speculated that the carabiner clipped to the bolt hanger flipped and became cross-loaded while A.L. was working on the difficult, overhanging moves. The carabiner was still in one piece with the gate attached at the hinge but the other end was blown open and had come off the hanger.
有几个地方看不懂:
1。flipped and became cross-loaded
2。come off the hanger
字面意思我知道,但到底是怎样的情形呢?
