[narrator] Analyzing
the onboard computer,
00:00:03.067 --> 00:00:03.092
the investigation discovered
that the boom
00:00:03.092 --> 00:00:04.004
the investigation discovered
that the boom
00:00:05.367 --> 00:00:08.009
was lowered five degrees
further than expected,
00:00:08.967 --> 00:00:11.003
and long before the jib
was anywhere near
00:00:11.367 --> 00:00:14.000
the ground,
the crane lost balance.
00:00:15.167 --> 00:00:18.466
With massive,
carefully balanced machines
00:00:18.466 --> 00:00:21.167
like this,
even a gust of wind that
00:00:21.167 --> 00:00:24.666
we might barely feel
can make all the difference.
00:00:24.666 --> 00:00:26.466
In the grand scheme of things,
00:00:26.466 --> 00:00:28.967
five degrees
might not seem a lot,
00:00:28.967 --> 00:00:33.007
but here this small amount
likely proved catastrophic.
