And people. But planes also made it possible for viruses to travel faster than ever before that turned a local outbreak into a Global Pandemic the Airline Industry was knocked out of the sky around 90 percent of Flights Canceled globally some airlines couldnt survive. Things are slowly taking off again but the future of aviation looks very Different Health screening has become as important as security screening social distancing and once crowded airport terminals and on board may be the new normal but how will the new normal ensure protection from a deadly virus that hasnt gone away. But come to the night in special until the news. And the last time i travelled by plane was in watch star scope too had just started to spread in germany and plane. Was soon grounded on the restrictions are being lifted and people us lowly taking to the skies again but is it safe. Birds chirping at the e used largest airport powerss shout to god. In unusual silence where 1300 flights used to take off and over 200000 passengers transit each day when they want to apply we saw a 98 percent fall in passenger numbers since the lockdown measures began to be eased we felt things moving a bit last week we had an average of around 10000. 00 passengers per day which is about 20 percent more than the previous week its much less than last year but we see an increase and some movement on the passenger side falsify me or anybody. In china where the pandemic 1st broke out the low point was mid february with only 23 percent of the normal flight. That is now stabilized at around 60 percent compared to the Previous Year but the industry fears passenger numbers will never reach the same levels. Of a campus as it were over passengers need a good reason to travel at the moment. We expect new measures from the government starting june the 15th. We now have passenger restrictions until that date and we expect a resumption of flights in the Schengen Area on the 15th. When you are there watching again is also money but before that happens passengers have to feel safe it would take years to equip aircraft with new seating plans and may never happen given the air carriers tight budgets for the time being travelers will need to bring a lot more patients with them in delhi baggage is disinfected outside the terminal all passengers are checked for temperature negative corona tests could be added to the list for passengers boarding in some countries. Cd on this flight is socially distanced. The flight attendants uniforms are also different. Experience wise to just sum it up if you ask me this is and yes it is overall different because we are not used to coming to work like this. And the job isnt over once the flight lands this cleaning team in delhi has to completely just infect the aircraft. So is the coronavirus the kiss of death for traveling or can we reduce the risks of catching a dangerous disease and bring in professor srinivasan from the department of Computer Science at the university of west florida good to have you with us and i understand that you are the Principal Investigator of new research on pig destry and dynamics models and that has recently been used in the analysis of procedures to reduce the risk of disease spread in airplanes in terms of health how risky is it to fly well if you look at one specific flight or one specific good on up what a flight the risk of infection is not very high oh up country going to so many travel and so many flight its inevitable a sometime or the other there will be a major outbreak on the flights so Nothing Happened and sod all souls so there are most of the flights going in fact or anyone else but there were a few flights where a lot of people got infected so so the risk of getting infected on a plane isnt higher than lets say ah on a train or if any room that is closed. Yeah. I dont want to give exact numbers because in a new outbreak its always very difficult to predict whats going to exactly happen but because of the largest number of flights so you have a high probably of some outbreak of it happening over the whole system well lets take a closer look at sars cove 2 virus because obviously one way to reduce the risk of catching a virus is social distancing that is pretty impossible on a plane isnt it. To social distancing is not a all or nothing thing its not like for example there you go talk about the 6 feet threshold. If youre much closer the product of infection of much higher and sometimes you can get you can catch it even if you have fathered r. V. So others can do certain things you know for example some of the lines of removing go a bit of people in the middle c. So that includes sort of the sensing a bit if you look at a passenger you know they can been boarding they can actually try to maintain distance for example if you board lost you can try to maintain distance of the previous person and have some control over what happens so if everybody boards last then the plane will never take off and leaving out the middle seat is obviously not very Cost Effective for the airlines you did a lot of research certainly in in the way that you humans behave. In sort of Narrow Passage ways and you used from tear out which is one of the worlds most powerful Super Computers how did this computer help you with your simulations and what were your findings. Well one of the observations are that Human Behavior is very hard to predict so if you look at if you look at one particular simulation ought to to be simulations and try to see what really lumens do you have probably not going to capture all possibilities have made it in fact ill pick an extreme ever for the capture that you need to look at all possible ways in which humans actually behave so we do a google simulation we did millions of simulation so that picks a lot of computation a foot so that of the reason we have to use a supercomputer because we want to look at extreme events where unlike the situation of these 2 major infection 03. Given that a lot of people are starting to fly again because planes on the longer ground you already said its a good idea to be the last on board that might not always be possible anything else we should to bear in mind to step in a particular safe seat or row especially when we think of adventure lation and and droplets that carry by resists and them floating around. Where the typical model of just that sitting in the. Seat is most dangerous because one is you of course the people who actually walking and i and also the absolutely and most of the planes take the ad from the site into the site it does something it defers but on the whole it tends to move to ad words the person and i get infections in because infection probability and assad opaque yet yes go on. Well and saw so pretty though. One of the major outbreaks actually equally spread. In the middle seat so its not guiding to if you sit in the eye youre going to have a higher probability of the window youll have a lower probability. Of modeling support and some common sense that we know would be a little safer than that i know writes i know what i book next professor srinivasan from the department of Computer Science with you this city of west florida thank you so much for your time. Ok reza time for your questions now over to our science correspondent derrick williams. When we have a vaccine how can we provide enough shots to we not can i tell everyone is there a plan to coordinate efforts around the glenn. There are now over 120. 00 different kogut 19 vaccine candidates and studies going around the world and based on a range of technologies some developers are so confident of success that theyre theyre already making plans for large Scale Production the most likely scenario is that well need more than one successful vaccine to meet Global Demand and it could well be that different demographics like like children or the elderly respond better or worse to particular vaccines so so this shotgun approach is actually being viewed as a positive thing. Is there a difference between p. C. On tests and denies the tests. The p. C. R. Or polymerase Chain Reaction test is a method for for multiplying and tagging small amounts of genetic material like like r. N. A. From a swab sample taken for example from your nose or your throat when the genetic material and markers it carries are amplified a machine can detect it p. C. R. Is the primary method used to determine the presence of sars cove 2 so whether someone has an active covert 19 infection. Elisa which stands for enzyme linked abuse or been passe is whats called a serial logical test its a blood test for detecting antibodies made by your immune system in response to the virus and they take a while for the body to produce so so p. C. Or tests tell you if your pruett li infected while elisa tells you if you might have had the disease already at some point in the past and produced antibodies against it. And Eric Williams will be back to answer more of your questions tomorrow now there are some kinds of flight we might see more often in a pandemic the demand for groans to deliver medical supplies is said to fly higher this wynkoop copter can carry about 5 kilograms and fly well over 100 kilometers an hour it is being trial to at the moment to see if they can bring cargo like over 1000 test kits and personal protective equipment to remote scottish islands. Thats all fog of an audience special thanks for watching and before we go a helpful reminder for those of you planning to board a plane soon again be sure to bring a white if you were to disinfect surfaces plastic zip bags or personal items like your i. D. Card wash your hands as often as possible stay in your seat and wear a mask and in either case have a safe flight thanks for watching. Lots of Homeless People come out seen on the streets of. Tokyo a 100000 people used to spend their nights in internet cafes and. Among the u. K. But then the cafes had to close because of the corona. Virus. Someone can do know how to me find. Global 3000.
