[narrator] Each oversized
metal hinge consists of a casting attached
to the concrete spillway and a hinge plate
on the gate itself. Both connected by nearly
four inch diameter metal pins. If just one component fails,
the report stated, the results
could be catastrophic. Examining the destroyed gate,
the team found that
the hinge plates were missing, most likely ripped
from the pins

[narrator] Each oversized metal hinge consists
00:00:03.004 --> 00:00:06.005
of a casting attached to the concrete spillway
00:00:06.005 --> 00:00:09.006
and a hinge plate on the gate itself.
00:00:09.006 --> 00:00:13.299
Both connected by nearly four inch diameter metal pins.
00:00:14.533 --> 00:00:17.633
If just one component fails, the report stated,
00:00:17.007 --> 00:00:21.001
the results could be catastrophic.
00:00:21.001 --> 00:00:24.006
Examining the destroyed gate, the team found that the hinge plates were missing,
00:00:24.006 --> 00:00:27.199
most likely ripped from the pins.
