The snowcovered mountain in the background there is the hekla volcano itself. And here in the foreground this lightcolored layer there at the top was erupted from hekla 3,000 years ago. Narrator these ash layers tell thor a great deal about heklas explosive past.

Do you mind if i have a look . No, not at all, go ahead. Id like to have a look inside. Please do. Where i come from, you want to know how something works, you cut it open. Sony versus saw.

And 23 civilians die in part because of limitations of the sensors. But engineers are working to create new sensors that can see more, in greater detail, than ever before. Deptula today weve developed sensors that can watch with an allseeing eye and see an area about the size of a small city all at one time. Yiannis antoniades this is the next generation of surveillance. For the first time we actually have permission from the government to show the basic capabilities. It is important for the public to know that some of these capabilities exist. Narrator engineer Yiannis Antoniades designed the new sensor, known as argus. With 1. 8 billion pixels, its the worlds highest resolution camera. Argus fits inside this pod that attaches to the belly of a uav. But because much of the work is classified, we cant see the sensor itself. Antoniades because we are not allowed to expose some of the pieces that make up the sensors so you get t ....

We warn you from making anyding public or for notify the police. Its an odd way of writing. The dear sir ends with an exclamation point. The dollar sign is put after the dollar amount, which is a german way of writing the money. Also there are misspellings of words. The word signature is spelled singnature. Narrator but the defense expert using the same comparisons said hauptmann was not the author. So who is right . We might know if we had taken hauptmanns begg letter envelope, retrieved a dna sample from the licked flap and compared it to dna samples from the ransom note envelopes. But new jersey refused our request to do a dna analysis. Today handwriting analysis has become mo ....
