Cartoon of the Day… !!!
Joke For the Day… ” There is No Way… ” !!!
A man gets pulled over by the police for speeding.
The cop walks up to the car and says to the driver, “Sir, did you know that you were going 60 miles an hour?”
The driver says, “Officer, there is no way I could have been going 60 miles an hour!”
The cop says, “Really! Why is that?”
The driver replies, “I could not have been going 60 miles an hour because I’ve only been out driving for 25 minutes.”

உடல் எழுத்து
அதிகாலை எழு
ஆகாயம் தொழு
இருதயம் துடிக்கவிடு
ஈறழுந்தப் பல் தேய்
உடல்வேர்வை கழி
ஊளைச்சதை ஒழி
எருதுபோல் உழை
ஏழைபோல் உண்
ஐம்புலன் புதுக்கு
ஒழித்துவிடு புகைமதுவை
ஓட்டம் போல் நட
ஔடதம் பசி
அஃதாற்றின் எஃகாவாய்.

” You Think Our City Roads are More Congested ? … Watch this Video clip !!!”
Both Europe 24 and North Atlantic Skies were designed to give an overview of the daily complexity and volumes of air traffic across the UK and Europe and to do so in a way that was cinematic and exciting to watch. I think we were able to do that to great effect, but we now want to take you a little deeper.
We are therefore very excited to publish UK 24 – your guided tour to some of what makes UK aviation work.
Our airspace is busy, complex and there is a lot going on. Each year we manage around 2.2 million movements, peaking at over 8,000 a day (although there are around 7,000 on this particular day), with only 5.5 seconds delay per flight attributable to NATS. Obviously there are the flows of large aircraft from the airports into and out of the UK, but there is also a lot of activity outside controlled airspace. UK 24 is designed to help visualise the breadth and depth of UK aviation and why airspace is such an important asset.
The day starts with the bow wave of transatlantic traffic heading towards the UK on their organised and separated tracks. This is quickly joined by traffic from Europe and the first waves of departures from UK airports. Over a short period of time the traffic levels grow to show the main trunk roads of airspace as well as the hubs around London, Manchester and central Scotland.
We then move to give a unique view of the holding stacks over London and how they are a fundamental part of the Heathrow operation, providing the constant flow of traffic that makes it the world’s busiest dual runway airport with 1,350 movements a day.
Our tour then take us around the UK, including the other major airports, our two control centres in Swanwick and Prestwick, some general aviation traffic and examples of military training off the east coast of England and near to North Wales. We then dwell on the spider’s web of helicopter tracks that originate from Aberdeen, taking people and vital supplies to and from the North Sea oil and gas rigs.
We hope you enjoy this insight into the complexity and beauty of a day of UK air traffic and the value of airspace as the invisible infrastructure that makes it all work.
Value of aviation to the UK economy
The aviation sector and its supply chain generates over £20bn per year in economic output and directly employs circa 220,000 people. At Heathrow alone, goods worth £133 billion were shipped in and out last year, more than the combined value of goods transiting through the UK’s two largest ports, Felixstowe and Southampton.
Aviation is on average a much more productive sector than the rest of the economy; each pound spent on upgrading our aviation infrastructure is expected to generate over £5 in return. In addition aviation is a significant growth sector within key regions for UK trade, for example China, the Middle East and Turkey have ambitious plans to more than double their capacity.
Without additional capacity in the UK, we risk the rapid growth in traffic and its associated commerce being focused elsewhere.

Image of the Day…. ISS astronauts’ Space Walk Today… Feb 25…
Today’s spacewalk – the 2nd of 3 planned – began at 7:10 a.m. EST (1210 UTC) and will last 6.5 hours. This post has links to today’s live coverage, plus spectacular images from Saturday’s spacewalk.
NASA astronaut Barry Wilmore works outside the International Space Station on the first of three spacewalks preparing the station for future arrivals by U.S. commercial crew spacecraft, Saturday, February 21, 2015. Fellow spacewalker Terry Virts, seen reflected in the visor, shared this photograph on social media.

Today – February 25, 2015 – beginning at 7:10 a.m. EST (1210 UTC), International Space Station (ISS) astronauts are performing the second of three spacewalks to prepare the orbiting laboratory for future arrivals by U.S. commercial crew spacecraft. NASA TV coverage has begun and will go until 2 p.m. EST (1900 UTC) Wednesday. Watch here
NASA astronauts Barry Wilmore and Terry Virts completed the first spacewalk on February 21 and the third is scheduled for Sunday, March 1.
The spacewalks are designed to lay cables along the forward end of the U.S. segment to bring power and communication to two International Docking Adapters slated to arrive later this year. The new docking ports will welcome U.S. commercial spacecraft launching from Florida beginning in 2017, permitting the standard station crew size to grow from six to seven and potentially double the amount of crew time devoted to research.
Ground controllers have maneuvered the space station’s large robotic arm Canadarm2 in place for work planned for Wednesday’s spacewalk. Spacewalkers Barry Wilmore and Terry Virts will start their spacewalk at 7:10 a.m. EST to lay more cables and lubricate one of Canadarm2’s two latching end effectors, which serve as tip or base for the robotic arm. They will also prepare the Tranquility module for the relocation of the Permanent Multipurpose Module and the new Bigelow Expanded Activity Module later this year.
All three spacewalks are in support of the long-planned ISS reconfiguration from its current configuration, which was designed to support visiting Space Shuttles, to its new configuration optimived for future visiting commercial crew and cargo vehicles.
While cargo vehicles attach to the ISS using the process of berthing, whereby they are captured with the station’s robotic arm and positioned below a berthing port prior to being bolted into place, commercial crew vehicles will not use this method.
This is because the process of un-berthing takes a long time to complete, since cables and ducting between the visiting spacecraft and the ISS must first be manually disconnected, control boxes installed, hatches closed, and then the visiting spacecraft must be maneuvered away from the station with the robotic arm.
This means that berthing ports cannot support a rapid evacuation of crew from the ISS should it ever be necessary, which will be one of the primary roles of the commercial crew vehicles as they serve as “lifeboats” during their crew’s stay at the ISS.
Instead, crewed vehicles will attach to the ISS via a process of docking, whereby the visiting spacecraft flies itself all the way into its docking port and attaches via a capture ring striking a corresponding attachment mechanism.
Bottom line: NASA astronauts Barry Wilmore and Terry Virts aboard the International Space Station completed the first of three spacewalk on February 21, 2105. The second is scheduled for Wednesday, February 25 and the third for Sunday, March 1. The astronauts are securing cables to prepare the orbiting laboratory for future arrivals by U.S. commercial crew.
