There are many good pocket cameras that take good quality pictures, in general it should be enough just to pick a price point, and go with recent models from known brands: Canon, Nikon, Pentax, Panasonic, Olympus, and a few others.
I should point out that the size of the camera is very important. If you ever have to think "should I take the camera or not", your camera is not the right size for the job.
You are talking about the immediate context, but there's more than one layer to consider. More importantly: nobody gets to decide what is offensive to somebody else.
I'm sure that someone else at LHC thought of this, but you can't send radio signals through the earth like neutrinos. So the distance from the control mechanism to the antenna on the top of the building, should be about, say, 18m, right? (plus any curve in the earth's surface, assuming that the receiver is over the horizon.) This really sounds like an error in measurement, repeat with a receiver on the moon.
Antenna? Over the horizon? Please, do some back-of-the-envelope calculations. Furthermore, 18m is an absolutely enormous distance for today's positioning tools. It was an enormous distance 100 years ago!
That is not very impressive, since the glow from a CRT is enough to reconstruct the image on the screen.
I do this every day using organically grown Eyeball technology, in fact.
But seriously, people screaming for help are not drowning (yet). People who are actually drowning, on the contrary, are quietly fighting for their life. The lungs are used for breathing, and when you can't get enough air to stay alive, as an automatic response none of it will be spent on speech or other vocalisation.
IANADoctor but I can't think of a medical emergency that causes that sort of erratic manoeuvring, passing out certainly doesn't. Moreover, the plane was already in trouble, since the pilot called in a mayday and started to pull up according to protocol when the fatal problems happened. Mechanical failure is simply more likely at this point: video showing the sequence of events
What is algebra, exactly? Is it one of those three-cornered things? -- J.M. Barrie
