It was supposed to be a routine mission for U.S. Air Force Lt. Col. Darrell P. Zelko, a veteran pilot of the 1991 Gulf War. The weather over the capital city of Serbia was stormy on the night of March 27th, 1999, and only a few NATO planes were in the sky to enforce Operation Allied Force. Zelco was to drop 2 laser guided munitions and get back to his base in Italy.
There was no way for him to know that at exactly 8:15pm local time, a young Colonel of the Army of Yugoslavia had done what was thought to be impossible. His men had seen Zelco’s unseeable F117 Stealth Fighter.
Seconds later, a barrage of Soviet 60’s era S-125 surface-to-air missiles were screaming toward him at three times the speed of sound. One hit. Colonel Zelco was forced to eject while his advanced stealth aircraft fell to the ground in a ball of fire. It was the first and only time an F117 had been shot down. He would be rescued a few hours later.
How did they do it? How could a relatively unsophisticated army using outdated soviet technology take down one of the most advanced war planes in the world? A plane that was supposed be invisible to enemy radar? As you can imagine, there are several theories. We’re going deep with the “what-ifs” on this one so join us after the break as we break down and explore them in detail.

Sometimes you need to sleep where you’re not supposed to. In this case, [MisterE] wanted to cut the costs associated with his climbing trips. He took a 2001 GMC Savana cargo van and turned it into a stealthy mobile living space. The project is from back in 2008 and we almost waved off from featuring it. But when you start to look at all of the creative space-saving solutions in the hack we think you’ll agree it’s worth a look.
Since he’s a climber that means time in the mountains, which can be quite cold. The sides and floor of the van were insulated to about R19 before the build work itself started and there’s a small wall-mounted heater. For comfort, a fouton was a must for sleeping but also for its double use as a sofa. For style the only choice here was bead-board to cover all of the walls. There is a small kitchenette that is mainly just a sink (we’ve seen running water in vehicles before). A couple of extra batteries power all of the electronics: audio, laptop, etc. When asked, [MisterE] confirms that he added hidden storage areas for his more pricey gear. Total cost on the project came it at $11,500. About nine for the van and the rest for improvements.
He mentions he blew an inverter because of grounding issues while starting the van. As long as he turns it off before start-up he’s fine. Shouldn’t there be a better way to build protection into this? Please leave a comment after the break and let us know what you’d do differently.
[Garrett] posted about ThinkGeek updating the Phantom Keystroker to support random capslocking. You may remember that [Garrett] built the Stealth USB CapsLocker for April Fool’s day. The tiny device would randomly turn on the victim’s Caps Lock. This update to the commercial product has inspired him to refresh his own design. He suggests few possible options: random inserts, erratic volume control, or random sleeps. He’s also planning on making it more accessible to hacking. What would you add?
