We had just such a chance in a short course, "Human Factors in
Aircraft Accident Investigations". The instructor is an ex-NASA
employee who now works as an aircraft accident investigator (usually
hired by the insurance companies or the pilots families) and several
of the students had spent a fair amount of time working on the decks
The ship was in the middle of night carrier ops, trying to launch
every plane they could quickly, and this plane was a reserve bird,
which put the crew a little bit behind the power curve. The
unfortunate fellow was on his way to the front of the A-6 and he took
the wrong route, which put him right in front of the inlet with the
engine in MIL, which it shouldn't have been at that point in the
evolution. The aircrewman had turned slightly to glance into the
engine, something he'd done before. Whoosh! In he went, completely,
in just a blink of the eye. The rest of the plane crew carried on
with what they were doing. Almost immediately, first sparks and then
flames spat out the back of the engine. Someone noticed this, not
quite immediately, and the pilot was signaled to shut it down while
the crew ran around with extinguishers. Eventually, after what seemed
like forever but was actually about four minutes, the fellow backed
out of the inlet and fell on the ground, but no one noticed at first.
When they finally did notice, they rushed over, some going to him and
at least one other peering into the inlet.
The engine didn't stop until the pilot shut it down at the crew's
signal, although it was badly FODed.
The next thing on the video was the beginning of a broadcast on the
ship's TV channel, with the poor fellow, who wasn't actually injured,
and an officer, maybe the ship's safety officer, that was made a few
hours later. The poor fellow was obviously totally out of it--he was
still trembling, he couldn't hear anything said to him, his eyes
weren't fixing on anything, and he really couldn't talk coherently.
We didn't get to see much more of the broadcast, as it had little to
do with the point the instructor was making, but it made a real
Here's the text of a post I made here fourteen months ago, just after
the class, when the topic came around on the newsgroup for the third
or fourth time. I fished this out of Deja News with a power search,
using the key words "A-6" and "inlet" and specifying this newsgroup.
A similar search might not be too bad an idea for people with
questions to begin in general.

Not only was it non-fatal, but the guy climbed out himself (the rest
of the crew didn't even know he was in there) and appeared, fairly
shortly thereafter, on ship's TV in an interview with a safety
officer. His gyros were pretty obviously uncaged at that point.
I saw the ingestion and interview video about six weeks ago, in a
class on human factors in accident investigation. Needless to say, we
discussed it in some detail.
The guy was supposed to do something at the nosegear (hook up the
launch bar, maybe?). Rather than coming in behind the inlet and then
forward under the plane, he walked in front of the inlet. He'd done
this frequently, stating that he was even in the habit of actually
looking at the engine as he went by. This wouldn't have been a
problem, except that the A-6 driver was in MIL power, I think because
it was a reserve bird and he was scrambling to catch up for the
launch, which he shouldn't have been at that time and place. Anyway,
the guy's cranial (and flashlight?) went through the engine and
destroyed it, which is why he wasn't even injured, except for being
snatched off his feet and dragged into the inlet. His hearing was
pretty bad in the interview, but we were told it recovered. Anyway,
the engine pretty much blew up and the rest of the crew were scurrying
around, not knowing he was there, and he came climbing out very
slowly. He slipped out of the inlet, stood there for a second, and
then collapsed. About then, someone finally saw him and rushed to
The video is very deceptive, because it was really quite dark, rather
than just dim, which you'd think from the tape. That no one knew he
was in there wasn't really surprising, according to other class
members who had worked on carrier flight decks.
