FIVE WAR HEROES WHO ALSO HAPPENED TO BE DOGS
Heroes come in many forms; some are even furry and four-legged. Due in part to their superior ability to sniff and hear trouble, dogs have long been a fantastic ally and a great protector of humans. After all, it was Lassie who, through a series of barks, told the grown-ups that Timmy was in trouble again (Note: Timmy never actually fell down a well. Mineshaft, sure, but no well.) Dogs can also be quite brave and have been known to run into dangerous situations without a moment of hesitation. Throughout history, several dogs have gained a reputation as being courageous in wartime.
Here are the stories of five such dogs that became war heroes and helped saved human lives:
Gunner – Australia’s Alarm
Under a destroyed mess hall, they found the smallest survivor of them all, a six-month-old male stray kelpie (an Australian sheep dog). He had a broken leg and was whimpering. Eventually, the injured pup ended up in the hands of Leading Aircraftman Percy Westcott. He made it his duty to get this dog help. Westcott took the dog to the doctor, who said he couldn’t treat any “man” who didn’t have a name or serial number. So, Westcott named the kelpie “Gunner” and gave him the number 0000. Satisfied, the doctor put a cast on Gunner’s leg and set them on their way.
From that point forward, Gunner and Westcott were inseparable. When Gunner’s leg began healing (despite his habit of chewing the cast), he would join Westcott on his daily tasks. One day not long after the attack, as the men worked on repairing several planes in the airfield, Gunner started barking and jumping up and down. The men paid no attention to the dog, but within a few minutes Japanese raiders swooped in and commenced shelling Darwin again.
Luckily, the men and Gunner managed to dive to safety, but it was another surprise attack. Well, to everyone but Gunner. In general, Australian Kelpie hearing, even more so than many other breeds of dogs, is fantastic. Two days later, Gunner again started making a commotion. This time, the men knew to find cover and prepare for the upcoming attack.
From February 1942 to November 1943, over sixty air raids were commenced on Darwin. Gunner warned the soldiers of nearly every one, saving countless lives. Another amazing aspect of this was that Gunner never barked when Australian planes took off or were returning. He was able to differentiate between Australian aircrafts and Japanese aircrafts. It is not known what happened to Gunner after the war.
Rip the Rescue Dog
Rip came out with King after a bombing one night and his nose started twitching. Rip followed the scent to a collapsed building and started digging. What Rip found was a man, still alive, buried beneath. It was probably the best image this man had ever seen; a barking, sniffing mutt.
Despite never being formally trained, Rip became England’s first urban search and rescue dog. It was reported that he found and rescued over hundred people with his sensitive, life-saving nose. Due to Rip, today London’s police force and military trains hundreds of dogs per year to be part of their urban search and rescue teams.
In 1945, Rip was awarded the Dickin Medal for bravery, an honor bestowed animals for their service during war. On the medal, it reads “For Gallantry. We Also Serve.” Rip passed away in 1946 and is buried in Ilford Animal Cemetery in London.
Antis – The “German” Who Saved Frenchmen
Antis, named so because Bozdech loved to fly Russian ANT dive-bombers, became not just a loyal friend, but a seasoned war veteran. Much like Gunner, he barked in warning about oncoming enemy fire. Just like Rip, he learned how to sniff and dig for survivors. Robert and his comrades also considered Antis a good luck charm and, most importantly, braver than many a human soldier. He would hide away in Bozdech’s gunner plane to ensure that he would be there to protect his pal. Antis would also run into enemy fire to notify others where the injured men were. He was even once injured himself, yet that didn’t stop him from performing his duties. Several days after being injured, he somehow snuck onto Bozdech’s plane as a stowaway.
After the war, Antis was also awarded the Dickin Medal and lived with Bozdech the rest of his life, passing away at the age of 14 in 1953.
Salty and Roselle Safely Guides on 9/11
Roselle was asleep when the plane struck the 99th floor. Calmly and cooly, she guided Hingson, and several others in the office, down over 1400 hundred darkened stairs and out of the door. The whole escape took about an hour, but within moments of making it to the street, Tower 2 collapsed, sending debris everywhere. Roselle was struck by pieces, but she was unfazed and continued moving, just like she was trained to do.
As Hingson said,
She saved my life. While everyone ran in panic, Roselle remained totally focused on her job. While debris fell around us, and even hit us, Roselle stayed calm.
Salty had always loved fast-paced, city-living. When he was introduced to Omar Rivera, it was a perfect match. Rivera had gone blind due to glaucoma, but continued to work for New York’s Port Authority as a senior systems designer. He was working on the 71st floor of the World Trade Center Tower 1 on 9/11. Salty was lying next to Rivera when the plane hit. The whole building swayed, but Salty calmly got up, offered Rivera his guidance, and lead them down the stairs. At one point a co-worker, thinking the dog needed help, tried to take Salty’s leash, but he refused to leave his master’s side. They made it out the door and were two or three blocks away when the second tower collapsed.
Both Salty and Roselle were given the Dickin medal for their heroics despite all the chaos around them. Salty passed away in 2008 and Roselle in 2011. They are remembered as American heroes.
15 FASCINATING CELL PHONE RELATED FACTS YOU PROBABLY DIDN’T KNOW
1) The Name: “Cellular phones,” or more common today “cell phones,” get their name from the fact that areas served by towers are divided up into “cells.” The first use of the word “cellular” in this fashion was in 1977. The first documented use of the word “cell phone” was in 1984.
2) The First: On April 3, 1973, a Motorola employee, Martin Cooper, publicly demonstrated the world’s first handheld mobile phone by placing a call to Joel Engel, the head of research at AT&T’s Bell Labs using the phone. Engel and his team were Cooper’s chief rival and had also been attempting to make the world’s first handheld mobile phone. As Cooper stated, “As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973, there weren’t cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter – probably one of the more dangerous things I have ever done in my life.”
3) The Phone: This first handheld cell phone weighed 2.4 pounds and was 9 x 5 x 1.75 inches in size. For reference, the iPhone 6 is 5.44 x 2.64 x 0.27 inches and weighs just 129 grams (0.28 pounds) This first handheld cell phone also had only 20 minutes of battery life when talking, but as Martin Cooper stated “that wasn’t really a big problem because you couldn’t hold that phone up for that long.” Once the phone battery was drained, it took approximately 10 hours to charge back up fully.
4) The Fanboys: Although Apple’s iPhones generally receive the most hype and publicity, world-wide approximately 88.3% of all mobile phones in use today are not iPhones. Further, Android is king by far in terms of OS used on smart phones with a whopping 84.7% market share according to Business Insider (August 15, 2014).
5) The Fear: The fear of having no cell phone signal or otherwise being unable to make or receive cell phone calls is called Nomophobia.
So if there are no muscles in our fingers to move them, how do they move? Short answer: magic… err, tendons and ligaments. Longer answer: Each finger consists of three bones (phalanges). In our bodies, tendons generally connect muscle to bone, and ligaments generally connect bone to bone. The tendons that control the bones in our fingers are attached to 17 muscles in the palm of your hand and 18 in your forearm, with none of the muscles extending into the fingers.
7) The Texts: Over 9 trillion text messages were sent in 2013. That equates to about 1,200 text messages per person on the planet per year. However, text messaging numbers are starting to decline as people more and more use apps like WhatsApp, iMessage, etc. to communicate. Further, the number of text messages still pales in comparison to the number of emails sent per year, which is estimated at over 100 trillion.
8) The Fastest: According to the Guinness World Records, the current fastest texter in the world is Sonja Kristiansen of Norway who was able to text the following message in 37.28 seconds (fastest to date): “The razor-toothed piranhas of the general Serrasalmus and Pygocentrus are the most ferocious freshwater fish in the world. In reality, they seldom attack a human.” If you can beat that time, you might want to give Guinness World Records a call.
9) The Antiques: A type of car based non-handheld mobile phone has been around since the 1940s, but was more a novelty item than practical and generally needed significant enough power that you could only use one with the engine running.
11) The Most: The top 5 countries in the world with the most currently active cell phones are: China: 1.2 billion phones; India: 904 million phones; U.S. 327 million phones; Brazil: 276 million phones; and Russia: 256 million phones. That said, the highest number of active phones per person for a country is Montenegro at 192.5% or nearly two phones per person. The runner up on that list is Hong Kong at 187.9%.
A shift to cell phone usage has introduced the possibility of texting 9-1-1 to receive help. While the system is still being rolled out, many carriers such as AT&T, Sprint, T-Mobile, and Verizon now support this and it is expected that all will support it by December 31, 2014. To get around the problem of the individual sending the text knowing whether the texting 9-1-1 system is available in their area, if you send one where this isn’t available yet, you should receive an automatic response text message telling you it’s not available.
13) The Gap: It was a full 10 years after public demonstration of the first handheld cell phone in 1973 before the first commercial handheld cell phone, the DynaTAC 8000x (“Dynamic Adaptive Total Area Coverage”), hit the market on March 6, 1983. This phone weighed “only” 1.1 pounds, had 30 minutes of battery life (8 hours of standby), and was initially priced at $3,995, which is about $9300 today. It took another seven years to reach one million cell phone subscribers, hitting that figure in 1990. Today, billions of phones are currently in use and there are far more handheld mobile phone subscribers than there are wired phone subscribers.
