Many stories I've heard regarding alien machinery or back-engineered craft actually refer to the fact that the 'writing on the walls' is essential
to its operation. They're actually symbols of instruction that either allow it to operate or enhance its performance. I've heard of quite a few
cases where symbols were found, the most popular being Roswell. It was also most recently brought up again in the
CARET Drone hype/hoax and was
an integral part to the story.
The following is a clip from a Disclosure Project interview with
Brigadier General Stephen Lovekin in which he speaks specifically about
inscriptions on debris from a crashed alien craft. (fast-forward & watch 2:30 - 4:50).

There are a few reasons why it might have been included in this particular story, The Rainbow Conspiracy. The most
unlikely is that it's
actually alien in origin and very old. The metal's level of oxidation should have been a giveaway, and from what I've seen in the photo it was well
intact.
Another reason could be that the creators of the story wanted it to be more believable or interesting to true UFO aficionados. A witness account of
symbols or writing on strange equipment requires further investigation, and if deciphered would solve the mystery. However left in as a side note, it
only adds to the mystery.
The most likely scenario (assuming alien technologies have been recovered by the government at some point in the past) would be that this equipment
actually is a failed government project. However it's the nature of the project that's in question -- if it did indeed have symbols on it,
then its purpose wasn't exactly what was reported on that government website. The designing engineers were hoping it would do something spectacular,
and they were basing their hopes on what the original was able to do. Unfortunately, it looks like they might have tried to mix alien & human
technology and also improvised some of the mechanics. Aside from being a failed project, it could have been a complete disaster resulting from its
unpredictability, hence why it was buried. (Google 'Montauk Project' for an example). But I personally can't see why there would be any mention of
it anywhere on any official government site -- maybe this was just the government covering their butts after it was discovered.
Who knows? But I'd say there's a bit more to the story than we've found so far.
