What was happened? Kelly was bent.

We just got photo from our friend sharing these images of Kelly which was bent from parted drillstring.
This is the details.

While working the stuck drillstem using the kelly rig system, maximum tensile load applied on surface was about 375 Klb (170 tonne)  and the over pull was about 155 klb (70 tonne) and then the drill pipe was suddenly parted. This resulted in the Kelly to pop out of rotary table and the swivel bail came out of the hook. Therefore, the Kelly fail down freely because there was nothing to hold it. The equipment went down with the Kelly which was bent due to falling action from the rotary table to outside of the rig floor. Fortunately, nobody got injured from this incident.
