Aerial refueling, also called air refueling, in-flight refueling (IFR), air-to-air refueling (AAR) or tanking, is the process of transferring fuel from one aircraft (the tanker) to another (the receiver) during flight. Aerial refueling allows aircraft engines to receive fuel while in flight and today it is common for many large air forces. It is the equivalent of refueling your car by connecting it to a tanker truck while driving down the highway at high speed. In the rigid flying boom system of aerial refueling, the pilot of the receiving aircraft flies behind and below the tanker for refueling. To complete an aerial refueling, the tanker and receiver aircraft rendezvous, flying in formation. The receiver moves to a position behind the tanker, within safe limits of travel for the boom, aided by director lights or directions radioed by the boom operator. Once in position, the operator extends the boom to make contact with the receiver aircraft. Once in contact, fuel is pumped through the boom into the receiver aircraft. While in contact, the receiver pilot must continue to fly within the "air refueling envelope," the area in which contact with the boom is safe. Moving outside of this envelope can damage the boom or lead to mid-air collision. When the desired amount of fuel been transferred, the two aircraft disconnect, and the receiver aircraft departs the formation. While not in use, the boom is stowed flush with the bottom of the tanker's fuselage to minimize drag. Despite all the technological advances, commercial aircraft designers never adopted aerial refueling. They preferred to build aircraft with large internal fuel tanks because this was cheaper than operating a dedicated fleet of aircraft that simply served as flying gas tanks. Aerial refueling is now exclusively a military operation.

Is it a thrilling leisure activity or a dangerous sport? It is probably a combination of the two. Rafting or white water rafting is a challenging recreational outdoor activity using an inflatable raft to navigate a river or other bodies of water. This is usually done on white water or different degrees of rough water, in order to thrill and excite the raft passengers.
Since it began in the 1970 it has certainly become a lot safer with legislated safety measures, better qualified operators and much improved equipment. In the past, rivers have been known to swallowed up whole expeditions. Nowadays the overall risk, when using experienced operators, is considered as low. It is also now a competitive sport with international and world championship events. This competitive element of rafting began in the mid 90's.
One of the best white water rafting places all around the world is Zambezi River in the Victoria Falls that has brute and splashing waves, making rafting experience wild and aggressive. The long rapid, obstinate gradients and highly build-up pressure is sure to send a chill down the spine.
A famous traveler once described adventure as, “pursuit of life“. This thirst for adventure is no more the feed meant for few daring spirits. And there is no better way to celebrate life than going on an adventure holiday. Among all other adventure rides, white water rafting undoubtedly ranks ahead, because of the degree of thrill and excitement associated with it.

Tropical Islands Resort is an artificial tropical resort in Brandenburg, Germany.
It is the world's third largest building, and is the world's largest single hall without supporting pillars inside. Inside, visitors will find an exotic environment with rain forest, beach, artificial sun, palm trees, orchids, and bird soundtrack. It resides inside a disused hangar. The hangar cost €78 million and was originally commissioned by Cargo lifter AG as an airship hangar, but the airship it was intended to house was never built.

Tropical Islands stretches across an area of 66,000 m², the size of eight football fields. It has perfect temperatures of 26 °C and is home to the world’s biggest indoor rainforest. It presents authentical tropical vegetation with 500 different plants and allows insights into the cultures of Brazil, Bali, Thailand, Malaysia and Kenya.

It is unquestionably the most exclusive ride in the world: the gleaming, blue-and-white jumbo jet that answers to the call signal Air Force One. No matter where in the world the US President travels, if he flies in an Air Force jet, the plane is called Air Force One. Technically, Air Force One is the call sign of any Air Force aircraft carrying the President. It’s an American icon, as recognizable as the Statue of Liberty or the Grand Canyon. Air Force One is one of the most recognizable symbols of the presidency, spawning countless references not just in American culture but across the world. Emblazoned with the word "United States of America," the American flag, and the Seal of the President of the United States, it is an undeniable presence wherever it flies. Capable of refueling midair, Air Force One has unlimited range and can carry the President wherever he needs to travel. The onboard electronics are hardened to protect against an electromagnetic pulse, and Air Force One is equipped with advanced secure communications equipment, allowing the aircraft to function as a mobile command center in the event of an attack on the United States.
 

Operation Entebbe, also known as the Entebbe Raid or Operation Thunderbolt, was the counter-terrorism hostage-rescue mission carried out by the Israel Defense Force at Entebbe Airport in Uganda on the night of July 3 and early morning of July 4, 1976 against one of the worst terrorist hijackings in history.
Operation Entebbe was a hostage-rescue mission carried out by the Israel Defense Forces (IDF) at Entebbe Airport in Uganda on 4 July 1976. An Air France plane with 248 passengers was hijacked by Palestinian terrorists and supporters and flown to Entebbe, near Kampala, the capital of Uganda. Shortly after landing, all non-Jewish passengers were released. Negotiations went on for a week, until suddenly Israeli forces burst into the airport terminal with total surprise. The operation took place at night, as Israeli transport planes carried 100 elite commandos over 2,500 miles (4,000 km- Can you imagine?) to Uganda for the rescue operation. The operation, which took a week of planning, lasted 90 minutes and 103 hostages were rescued. Five Israeli commandos were wounded and one, the commander, Lt Col Yonatan Netanyahu, was killed. For the whole operation they lost only one commandor. All the hijackers, three hostages and 45 Ugandan soldiers were killed. As a result of the operation the United States military developed highly-trained rescue teams modeled on the Entebbe rescue.
The clear message sent: If the crocodile comes looking for appeasement, we’ll feed him a live hand grenade.
Israel says "We say to the terrorists of today: we did it then and we can do it now if we want."
These days, when we are in the midst of an ongoing battle against terrorism, violence and incitement, Operation Entebbe will always remain a shining example of the fight against terrorism and a symbol of man’s courage in resisting brutality and evil.If you are interested to know more about this operation, watch the movie “Raid on Entebee” based on true story.

Mossad, Israeli foreign intelligence service, is often regarded as one the most effective and well-informed intelligence organizations in the world. Mossad is responsible for intelligence collection and covert operations which are suspected to include targeted killings and paramilitary activities beyond Israel's borders and protecting Jewish communities worldwide. Its director reports directly to the Prime Minister of Israel . It has agents in all important countries around the world. Its activity is diverse, and varies from silent operations like monitoring individuals and organizations, to manipulating journalists, politicians and organizations, to the kidnapping and killing of individuals against Israel.

Russian Northern coast is a vast territory that lays for a few thousand of miles and all this coastline is inside the Polar Circle. Long polar winters mean no daylight at all; just one day changes another without any sign of the Sun rising above the horizon. There is only polar night for 100 day a year. But across this Northern coast there was always a short way for the cargo boats to travel from Eastern part of Russia to the Western. Now this trip can be made fairly easy with the appearance of all the satellite navigation equipment like GPS and others, but during the Soviet Era they had none of this.

So, the Communist Party of the Soviet Union decided to build a chain of lighthouses to guide ships finding their way in the dark polar night across uninhabited shores of the Soviet Russian Empire. They had to be fully autonomous, because they were situated hundreds and hundreds miles away from any populated areas. After reviewing different ideas on how to make them work for years without service and any external power supply, Soviet engineers decided to implement atomic energy to power up those structures. So, special lightweight small atomic reactors were produced in limited series to be delivered to the Polar Circle lands and to be installed on the lighthouses. Those small reactors could work in the independent mode for years and didn’t require any human interference. It was a kind of robot-lighthouse which counted itself the time of the year and the length of the daylight, turned on its lights when it was needed and sent radio signals to near by ships to warn them on their journey. It all looks like ran out the sci-fi book pages, but so they were.

Then, after the collapse of the Soviet Union, the unattended automatic lighthouses did it job for some time, but after some time they collapsed too. Mostly as a result of the hunt for the metals like copper and other stuff which were performed by the looters. They didn’t care or maybe even didn’t know the meaning of the “Radioactive Danger” sign and ignored them, breaking in and destroying the equipment. It sounds creepy but they broke into the reactors too causing all the structures to become radioactively polluted.
