FBI Director: COVID Pandemic Likely Caused By China Lab Leak; The Future Of Travel.

COY WIRE, CNN 10 ANCHOR: Hello, lovely people. Happy Friday eve. It`s Thursday, March 2nd. I`m Coy Wire and we are so grateful that you`re

spending part of your day with us right here on CNN 10.

Let`s start today with the latest reporting on the origins of COVID-19. It`s been nearly three years since the pandemic began and we`re still

trying to figure out answers about how exactly this virus was able to infect so many people and take so many lives.

Reporting this week states that with, quote, low confidence, the U.S. Department of Energy and the director of the FBI endorse a lab leak theory,

meaning the virus accidentally escaped from a lab in Wuhan, China. Low confidence according to the office of the director of national intelligence
 

confidence [ˋkɑnfədəns] n. 把握

generally means that the information is scant, questionable or very fragmented or that the intelligence community has significant concerns
 

scant [skænt] adj. 不足的；贫乏的；少量的

questionable [ˋkwɛstʃənəb!] adj. 可疑的；成问题的；不确定的

about the sources.

One of the main reasons that there is so much uncertainty about the virus`s origins is that China has not been transparent and willing to communicate

openly with their knowledge and information.

Now others within the U.S. intelligence community and many scientists maintain however that this virus developed naturally in animals and then

started to spread to humans in an outbreak at a market. Republicans in the House of Representatives on a COVID subcommittee are committed to

investigating the issue and finding the origin of the virus.

Here`s CNN chief investigative correspondent Pamela Brown with more.

PAMELA BROWN, CNN CHIEF INVESTIGATIVE CORRESPONDENT (voice-over): More than three years after the start of the COVID-19 pandemic. The theory that

the virus originated from a lab in Wuhan, China in the spotlight. The Department of Energy now saying in an updated classified report, that it
 

in the spotlight 引人注目, 成为关注焦点

believes with low confidence that the virus accidentally escaped from a lab, but that theory remains a minority opinion within the U.S.

intelligence community.

JAKE SULLIVAN, U.S NATIONAL SECURITY ADVISOR: Some elements of the Intelligence Community have reached conclusions on one side, some on the

other a number of them have said they just don`t have enough information to be sure.

BROWN: Early in the pandemic, many prominent scientists discredited the so-called lab leak theory. One group writing a letter published in The
 

discredit [dɪsˋkrɛdɪt] v. 不信，怀疑

Lancet Medical Journal saying, "We stand together to strongly condemn conspiracy theories suggesting that COVID-19 does not have a natural

origin."

But other medical professionals have long refused to rule it out.
 

rule ... out 排除 ...可能性

DR. SCOTT GOTTLIEB, FORMER FDA COMMISSIONER: These kinds of lab leaks happen all the time, actually, even here in the United States, we`ve had mishaps.
 

mishap [ˋmɪs͵hæp] n. 不幸事故；灾难

And in China, the last six known outbreaks of SARS, 1 have been out of labs.

BROWN: Even Dr. Anthony Fauci, the longtime director of the National Institute of Allergy and Infectious Diseases, agreed it was possible.

DR. ANTHONY FAUCI, DIRECTOR, U.S. NATIONAL INSTITUTE OF ALLEGERGY & INFECTIOUS DISEASES: It might possibly have been something that Chinese

were doing a virus that they isolated in the wild, and we`re having it in the lab and then somehow it escaped out. I don`t think that happened, but I

have an open mind.

BROWN: According to the intelligence community`s assessment, first published in 2021, the origins of the virus will remain elusive until China
 

elusive [ɪˋlusɪv] adj. 难以理解的

cooperates with global investigations.

Why at this point, do you say it`s possible maybe even probable that the virus came from a lab and accidentally leaked out?
 

probable [ˋprɑbəb!] adj. 很可能发生的；很可能成为事实的

JAMIE METZL, SENIOR FELLOW, ATLANTIC COUNCIL: The SARS-CoV-2 virus has an ancestral origin and a type of horseshoe bat, that doesn`t exist in Wuhan.
 

ancestral [ænˋsɛstrəl] adj. 祖先的；祖传的

If this comes from nature, there would have to be some evidence of it coming from nature. Right now, we don`t have that evidence.

BROWN: Now, House Republicans are demanding more information from the State Department, FBI and DOE on the origins of COVID-19.

REP. BRAD WENSTRUP (R-OH): I want to make sure that we are readying ourselves for the next pandemic. If we will and the more we can learn about

natural origins and/or possible lab leak, then the better off we`re going to be.

WIRE: Ten-second trivia:

An object traveling at a supersonic speed is traveling faster than -- 200 miles per hour, the speed of light, the speed of sound or the speed of a hedgehog?
 

hedgehog [ˋhɛdʒ͵hɑg] n.【动】猬，刺猬

Here comes the boom, a supersonic object is traveling faster than the speed of sound.

Continuing now with our series on the future of travel, we take to the skies where one company says that they`ll be able to take passengers in

planes that fly twice as fast as commercial planes being used today. And that means getting to where you`re going twice as fast.

But here`s the thing, you`d have to be willing to break the sound barrier to do so and that means you`d be going so fast that the aircraft would

create a sonic boom which according to NASA is as loud as an explosion or thunderclap.
 

sonic boom 音爆

thunderclap [ˋθʌndɚ͵klæp] n. 雷鸣；霹雳

Here`s CNN business correspondent Rahel Solomon with more.

(BEGIN VIDEOTAPE)

RAHEL SOLOMON, CNN BUSINESS CORRESPONDENT (voice-over): Planes are a ubiquitous mode of transportation today. They`ve allowed us to link cities,

countries and continents like never before. But what if we could fly faster and experience more in a way that`s also better for the planet.

BLAKE SCHOLL, CEO, BOOM SUPERSONIC: I believe in a future where more people can go more places more often. I think that life happens in person,

that connecting across oceans is incredibly important to our future.

I`m Blake Scholl, founder and CEO at Boom Supersonic.

The last frontier in air travel was more than half a century ago when we went from propeller aircraft into the jet age, and it`s been a long time

since we had a step forward.

I think the next frontier is all about making the planet more accessible, about having flights that are faster, more affordable, more convenient and dramatically

dramatically [drəˋmætɪk!ɪ] adv. 引人注目地

more sustainable.

SOLOMON: Just under a decade old, Colorado-based startup Boom is working to bring supersonic travel back to the skies.

SCHOLL: I started my career as a software engineer, but I`ve been passionate about aviation since I was a kid. And I never understood as a

tech guy why everything in our world was getting faster and better but our flights weren`t.

SOLOMON: Commercial supersonic air travel was first realized in the 1970s when Concorde took flight. But after just 27 years, the fleet was retired

due to a number of issues, including noise, expensive overhead and cost prohibitive tickets.
 

overhead [ˋovɚˋhɛd] n. 经常费用

prohibitive [prəˋhɪbɪtɪv] adj.（費用）高得負擔不起的，（價格等）使人望之卻步的

SCHOLL: The supersonic airplane fundamentally is about being able to go very efficiently at very high speed.

SOLOMON: Supersonic means flying faster than the speed of sound.

According to NASA, typical speeds for these aircraft range from about 1,200 kilometers per hour to about 2,400. These speeds are achievable through

powerful engines and a long lean fuselage design. The downside, supersonic travel creates a shock wave or sonic boom that is loud and disruptive over
 

fuselage [ˋfjuz!ɪdʒ] n.【空】飞机机身；飞机的骨架

land, which is why it`s only intended for long hauls across oceans.
 

haul [hɔl] n. 拖运距离

SCHOLL: We`re building on a proven foundation and delivering a new capability to passengers. It doesn`t require a massive regulatory change or

any regulatory change at all. We`ve now built XB-1 which is history`s first independently developed supersonic jet, and it`s going to be in the air

here in the next few months, to prove that all of this technology actually works.

SOLOMON: XB-1 is Boom`s prototype of what will be their first airliner Overture according to Scholl. It`s expected to be capable of going twice as

fast as regular aircraft therefore nearly halving transit times. Think San Francisco to Tokyo in six hours or New York to Frankfurt in a little over four.
 

halve [hæv] v. 将……减半

With orders already placed from U.S. carriers American and United, Boom has a sky-high goal to get Overture into service by 2029.

SCHOLL: On board the airplane, expect a large spacious interior and beautiful large windows it`s a supersonic airplane actually flies higher

you`ll be able to see the skies a deeper blue actually see the curvature of the earth. All of that adds up to a machine that can take you across oceans
 

curvature [ˋkɝvətʃɚ] n. 弯曲; 曲度

but at roughly the same cost as flying business class today. Ultimately, our goal is to make supersonic flight available to anybody who flies.

There are many challenges we still have left to overcome. What we`re doing is complex it`s safety critical it requires a lot of money. But when I look

back to the past, I also see a lot of challenges that we`ve already overcome. And that gives me encouragement that we will continue to do

things that the world says we can`t do.

Supersonic flight is about making the planet dramatically more accessible. When that happens, I think we will live in a very different, more peaceful,

more harmonious, more collaborative future.

WIRE: And for today`s story getting a 10 out of 10, teamwork makes the dream work for two eagles building. One is in the nest, then another flies

in is like, hey, can you help me with this other one`s like, what this stick? And it`s like, yeah, can you help me put it over there? Sure, no

problem. They pick up the branch and mark it over in perfect rhythm. If I give DJ Nader a beat, he can make them dance.

Now, keep in mind, these eagles get to get to be about three feet tall so their nests can get to be about six feet wide. That`s wider than a queen-

size bed. Well done, my feathery friends.

Well, that`s about all we have time for today. Thanks to everyone who`s reaching out @coywire on Instagram, Snapchat and TikTok, and thanks to

everyone showing love on our CNN YouTube page.

Northside High School in Jackson Tennessee, we see you and we are showing love right back at you.

Tomorrow`s Friday, can`t wait. Crush it today and go be awesome. I`m Coy Wire and we are CNN 10.
