Cessna C-172/C-41.

Most prolific aircraft Everbuilt.

The Cessna aviation company in the United States is one of the most prolific and successful for design and durability. Here we are going to look at this little light aircrat, which can be used for various multi-roles from Liason to Utility. From Training to Light Attack, and the there are hosts of other applications for this four seater.

Concieved in the 1950's this aircraft remains in production and is licence built in France by Reims, it is cheap to buy and to operate and is used by nearly every airforce, police and border security across the globe. It has enormous success in the civil market from pleasure flying to photographic observation and many more business and government uses.

It can be lightly armed with a 7.62mm gun pod and two to four rocket pods, some aircraft have been converted to operate with floats, while others as air ambulances or flying doctors. Developed from the O-1 Bird Dog a World-War-II design which came to fruitition in the late 1940's it is one of several designs that continue to operate such as the 152, Stationair, Caravan-I/II and the 337/0-2.

Segways.

The Two wheel Wonder.

The Segway is taking the world by suprise from the streets of the Czech Republic captial Prague to Thailands Bankok International airport. But many are now wondering how safe are these gyrocope controlled vehicles?

The Segway is perhaps the most prolific developmnet to compare to the invention of the bicyle, but it remains not as good and versatile as the bike. No seat and it is limited to short distant travel and depends very much on human balance technique.

With the further development of solar panels and digital guidance and stability platforms the Segway will perhaps have a further inpact, but it will in no way surpass the bicyle!

Hunters of the Sea. Part-One.

Fishing Industry.

Have you seen the two recent programmes on television in relation to what fishermen get up to at sea? The Catch and Trawler Wars open to the general public where our hake and cod today comes from and the risk endured daily by crews in all weathers at sea.

Fishing vessels come in all sizes from small one man and his fishing rod to factory ships, but generally they are in the Trawler class. These classes of vessels vary from nation to nation in how they are built and laid out, but they basically all try to do the same thing.

These two programmes and I am sure their are many other, reveal that the fishing industry is surviving on the edge. European quota's and many other International agreements do not benefit fishermen from individual nations, because it now allows others to fish in their waters and vise versa.

North-American Railroads. Part-One.

La Fayette to Amtrak.

To cover the United States and Canada is one thing, but in this series we will also look at Mexico. Amtrak is currently the main civilian passenger company for long-haul rail travel, while a few companies remain in the freight business. 

America has a long history of the railroads, following on from the United Kingdom and France 10 years after they were first invented. American carriage design has found itself employed on the British London Underground from 1911. meanwhile many early smaller locomotives were sent to Ireland for various narrow gauge adaptions.

The firsts trains brought from the U.K and France were as basic as you could get them, with carriages being adopted from the wild west stagecoach.

Space Exploration. Part-One.

New Discoveries.

I don't know about you! But I am fascinated by Space exploration from the Moon landings to this day I like to follow all the press releases from NASA, the Russians and the Europeans ESA. plus now we have the new additions of China and India to also view.

Since July Pluto the furthest out planet has been reclassified as a planet, after it was discovered to have a 80 km thick methane atmosphere by the New Horizons probe. The plutonian system has also five moons, while on Pluto moving ice shelves were also discovered.

Ceres in the asteroid belt has some strange bright spots and a pyramid shaped mountain. Recent closer flybys have revealed more of them, but still no explanation to what they might be? 

Meanwhile ESA images from Philae on a hurtling comet has revealed mass water ejections, as it nears the Sun. The Mars Rover Curiosity has discovered silica deposits and has had to back track its route up Mount Sharp.  This discovery rises the possibility greatly in the search for fossils

Last of all Russians trusted Progress robotic supply ship has softened relations between it and the United States. because there is now no other alternative way to supply the ISS, International Space station.
