One of the world's most revolutionary warplanes was retired in the Nevada desert Tuesday, and the I-Team was the only media crew there to see it.

The F-117 Stealth Fighters returned to the Tonopah Test Range, also known as Area 52, for what could be their final flights.

The planes, also known as the Nighthawks, were flown and tested at classified Nevada facilities for many years before the public even knew they existed.

Tuesday, the bat shaped, radar evading fighters flew from southern California to their final home at the base known as TTR, where they will be dismantled and stored.

The F-117's are still among the most advanced craft in the world, but have been replaced by the F-22 Raptors.

The I-Team , and a small group of aviation watchers, was the only ones outside of the base to witness the final landing.

"The end of an era, really, the Stealth Fighter coming home to TTR and being put in storage. They say they can reactivate them within a few days notice if they need to," said Dreamland Resort Webmaster Joerg Arnu.

Another reason the planes are being kept under wraps, the materials used to deflect radar are still highly classified.

Next week, George Knapp will take a look into the world of black projects and see if it's possible that something even more advanced than the F-22 raptor is being tested.
