[www.keralites.net] I think everyone at some point,

I think everyone at some point, goes through that one moment where they think my God, I can t do this .

But you know what?

You can. No matter how close you are to the edge, no matter how badly you feel like
giving up, or think it s best to do so rather than have to put up with
the pain - don t.
Don t lose hope that things will get better. Don t give up,
because there is someone out there who will make you smile in a way no
one else ever could. Keep that glimmer of hope alive in your heart,
because someone is out there searching for your smile. So wipe your
tears and keep your head held high.

Life is full of challenges, but these challenges are only given to you because God knows your faith is strong enough to get through them.

hold on and be strong.

[www.keralites.net] UNDER 6 HOURS

From America to Australia in Under 6 Hours

Just 100 years ago, getting from America to Europe was a voyage that took several days by ocean liners. With the invention of airplanes, that travel time was significantly shortened to under 24 hours. At the apex of the era of transatlantic flight, the Concorde was able to fly 100 passengers at mach 2.0 speeds from New York to London in just over 3.5 hours.

Now, the European Space Agency (ESA) just greenlighted the next stage of modern transportation – the hypersonic flight. The ESA has approved a new round of funding to project LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies).

Ignoring its funny name, the new plane will fly at mach 5.0 speeds (that's five times the speed of sound!), using liquid hydrogen engines. The planes will be able to travel from England to Australia in four hours, carry 300 passengers and even fly to space in just 15 minutes.

The new kind of engine is being developed by the British company Reaction Engines, who is said to invest over 60 million GBP in the development, and are going to start builing a full-scale prototype engine.

Current jet engines require that airplanes carry liquid oxygen as a coolant because in speeds beyond mach 3.0 the engines cannot use external oxygen for cooling. The new type of engine can use external oxygen freely, allowing it to cool down its engines from over 1,000°c (1,832°f) to -150°c (-328°f) in a fraction of a second.

Experts are hailing this development as the biggest advancement in aviation since the invention of the jet engine. The cost of a single plane is estimated to be a whopping $1.1 Billion and will have no windows.
