I wouldn't bet on it. Some types of capacitors degrade over time, especially if they are not used. Lubricants can migrate or turn to sludge. Electrical connections can corrode. A typical hard disk is designed for a 5-year service life.
My experience is that electronics equipment pulled out of long-term storage has a high failure rate.
I've noticed that in past news stories, such as the submarine the Russians lost due to a torpedo malfunction, some Russians will immediately blame "evil foreigners", without any evidence to back them up.
The problem isn't the design of the airplane, it's basic physics. Signal strength is inversely proportional to the square of the distance between the emitter and receiver. That means that someone's cheap CD player in the passenger cabin can easily jam a navigation beacon that is 50 kilometers away.
The problem could be fixed by redesigning all aircraft communication and navigation systems to use jam-resistant modulation techniques. Don't hold your breath waiting for that to happen. Voice communications still use AM. DME, VOR and ILS are based on ancient technology.
A perfectly shielded communication or navigation receiver is still a radio receiver, which can be jammed by passenger electronic devices. Consumer electronics equipment is designed to be cheap, not to minimize spurious emanations. Radio transmitters commonly have spurious emanations. They may be suppressed by a reasonable amount, but that may not be enough if they are near a receiver that is receiving a weak signal. Then there is interference caused by intermodulation. All you need are several strong signals and a nonlinear junction.
I've always thought that this is a golden opportunity for La Cosa Nostra. They could sell spam protection insurance. Get spammed? Guido will pay the spammer a visit and "explain" how spamming is not conducive to a long and healthy life.
One obvious application would be a rocket-assisted, ground-penetrating bomb or missile. They are already using old artillery tubes packed with explosives and fitted with guidance/steering units as "bunker busters". There is a lot of interest in weapons that can destroy deeply buried command and control facilities.
It is trivial to add support for scrubbing to the operating system. I've done this on embedded systems. I just added a small bit of code to the real-time clock ISR to read the contents of the next N addresses, where N was sized to guarantee that all of the installed ECC memory would be scrubbed at a reasonable rate. It didn't have any noticable impact on performance.
The telephone company can legally monitor telephone calls for maintenance purposes. A court order is needed for a wiretap used for law enforcement purposes.
Television sets with digital cable ready tuners will be introduced in the near future. This will allow you to watch non-premium digital cable channels without a digital cable box. I would expect them to eventually show up in PVRs.
With a properly designed air burst, the shockwave will bounce off the ground and combine with the primary shockwave, producing a stronger shockwave than would be produced by a ground burst, enhancing the blast damage.
Modern nuclear bombs are fitted with very effective parachutes that allow the plane to reach a safe distance before detonation. The weapon can be programmed for "laydown" fuzing, where the weapon detonates after a preset delay from the time of ground impact.
Some people have to receive their mail via a P.O. box, they may not have a choice about it. They may live in a rural area or other place where mail is not delivered to their home.
I have a dual processor 450 MHz G4 that runs on a "slow bus". It is more than fast enough for the average user. So it doesn't run at 3 Ghz. Do I care? No. Am I going to write a letter to Apple, complaining that they are losing the dicksize war? No.
The computer runs my applications without noticable delay,
is "user friendly", doesn't crash, and requires minimal maintenance. I'm happy with it.
While recently looking at HP's online store, I noticed the HP-48GX was listed as a "closeout" item. It appears that once the existing inventory of HP calculators are sold, HP will be out of the calculator business. Carly sucks.
Dishonest vendors have already done this in the past. There were motherboards with no cache that included a BIOS that lied about the presence of the cache.
A direction finding station produces a bearing to the emitter. You only need bearings from two stations to localize the emitter. Additional bearings will improve the accuracy of the solution.
Direction finding is why military commanders try to put their communications antennas at a distance from their headquarters and communications centers.
The Iraqi army may not have GPS guided missiles and bombs, but they do have rockets and artillery pieces. Being on the receiving end of an artillery barrage can ruin your whole day.
I get huge amounts of spam from South Korea, China and Russia. Almost all of it is in the language of the source country, advertising products or services that would only be of interest to people from those countries.
Most floating point calculations are already done in 64-bit (double precision) or 80-bit (extended precision). 32-bit (single precision) floating point is of limited usefulness on commodity Intel hardware.
I recently lost a laptop when the building it was in got flooded by runoff from torrential rains. Only the bottom of the laptop got wet, but that was enough to kill it. The manufacturer had made no effort to put waterproof seals on the various doors and access panels of the laptop.
That's tough to do. I once saw an electronics box from a tactical missile launcher in the repair shop. It made a sloshing noise when moved. Some bright G.I. had removed the cover from the dessicant cartridge holder and inserted a garden hose. The box did work after it was disassembled, dried out and reassembled.
A friend who worked in the radio repair shop reported less success with several radio sets that had been run over by tanks in the motor pool during vehicle maintenance.
The drive mounting and enclosure was a bit of a kludge. Are there any reasonably priced boxes that you can install the drives in, with the correct mounting hardware and backplane?

Also known as the Challenger School of risk assessment. We got away with it N times, it must be safe!

Some rockets use a gas generator to pressurise the fuel/oxidizer tanks, eliminating the need for turbopumps.

It's already been done, except for the paint part. The company went bankrupt.

The discone antenna is simple to construct and has very wide bandwidth.

They do explode, and they have caused casualties. Luckily, most of them end up detonating in open fields, without causing injury to people.
