Wow. State of the art equipment today (available to the public) is about the size of a pack of cigarettes.
It's a shame The Netherlands doesn't have overhead wiring. About 20 years ago, our local cops stuffed this kind of equipment inside dummy pole-mounted transformers (pole pigs in the utility vernacular). You get a much better view of the surrounding territory from a higher vantage point. Its also more difficult for the public to get a close look at it. I imagine street light fixtures are modded these days.
Before gathering data, you've got to design an experiment. Without understanding the measurements and statistics involved, the experiment design might turn out to be crap.
... is necessary for good experiment design. Trying to fix a poorly conceived experiment or bad data after the fact is like trying to cure diarrhea by messing with the bathroom plumbing.
Nobody at Boeing or the FAA seems to have genuinely evaluated the likelihood that the lithium ion technology has BUILT-IN liability in the basic concept.
Because that would take time to re-certify the entire electrical system. And it would put Boeing in a position of having to admit, "We were wrong." That, IMO, is the major issue. Once Boeing is wrong once, then all subsequent work they do could be second guessed.
The issue of fire containment isn't as difficult to demonstrate. We know the total energy stored in the battery. We assume it is converted to heat within some reasonably short time period. Someone whips out a slide rule and figures how much of that heat is conducted through the box versus expelled as hot gas outside the airplane.
No. This battery (the GS Yuasa cells) don't suffer from these sorts of failures in other applications. They are not a new product, built only for Boeing. So, unless we are to believe that GS Yuasa has been producing the units shipped to Thales from a special, substandard manufacturing line, this is not the cause.
The fireproof battery box solution solves one of two problems: It prevents an 'eventful' battery failure from propagating to other aircraft systems and components. It does not demonstrate the battery system reliability that Boeing had initially assumed in their certification analysis. If the demonstrated reliability to date is not sufficient for ETOPS operation, Boeing still has some homework to do. Failing to understand the nature of the faults means that Boeing cannot, with any certainty, claim to have reset the reliability numbers back to the original ones provided by certification analysis.
And all without having troops occupy Massachusetts, send armed UAVs in to take out targets in Boston and engage in a little 9 year occupation of Maine on the side.
We are concerned about intelligence indicating New Hampshire possesses nuclear technology, in spite of their continued claims tha it is for peaceful uses only.
Or not. The whole thing about separating and "improving your life" includes meeting new people. A year later and you and she (or he) may have done just this and moved on.
Relationships are about shared experiences (friends, lovers or whatever). If you avoid someone for a year (or more) you might just find that the two of you have moved in different directions.
That rotten egg smell they make is a sulfur compound. Maybe not all H2S (catalytic converters are capable of producing some bizarre molecular structures), but any decent chemist can clearly identify it by its smell.
So, that stinky sulfurous gas that they produce may turn out to be good for something after all. And here was, thinking that they were just an enviro-weenie plot to reduce the performance of muscle cars by restricting the exhaust system.
Most governments justify controlling $ACTIVITY because the alternative vacuum in regulation is quickly filled by organized crime and violence.
That's why, even though the taxi and other regulating bodies have the appearance of favoritism and inequity, they provide this without the firebombing of competitors businesses, mob hits and protection rackets of the alternative.
Just keep the gate to the elder care facilities locked. And question why grandpa, who needs a nurse to change his diaper, still has a valid drivers license and his Caddy parked out front.
Seattle came close to having a grade separated system that would have been an ideal candidate for full automation. It was to have been managed on its own, independant from the Metro bus and light rail bureaucracy, with the ability to negotiate its own labor contracts and to support itself financially.
The transit union public works taxing authorities killed it off.
Stingrays operated by company (a major DoD contractor) security services. They can monitor your calls and I'm pretty sure they could shut down calls to a blacklist of devices (or only permit calls from whitelisted devices).
Either the FCC doesn't care or they don't want to cross a major campaign contributor.
Its not necessarily the shape or the noise that give UAVs (and other such aircraft) away. Its the propeller and the high frequency modulation of radar or its optical signature that gives these away.
Because with actors, management doesn't have the option of replacing one George Clooney with a dozen nobodies from Hyderabad. And customers don't pay for the reputation or image of the 'star' creator (actor, director, etc.). So that becomes a commodity.
Or, using a sporting analogy, you can't replace one 350 pound linebacker with six 110 pound Chinese guys.

Nobody needs to count anything other then goals. And that should only take a two bit field, at most.
*Football, for all you non-USAians.

I'd tap that.

I'd like to keep the riff-raff out of my neighborhood. So I'll be marking a few streets as dead ends.
Diverless? Never happen. Thank the unions.

Yeah, but the other 70% do.
Please try another thought password. "Tits" is not sufficiently secure.

So then, it was take-out?
My kingdom for a +1 Funny mod point.
