Getting stuck in a traffic jam is ne f the mst bring prblems fr peple living in big cities.The fact that yu’re mving s slwly leads t stress,anger and the wish that yur car culd just fly ver the traffic like an airplane.

When the Olympics cmes t Ls Angeles in 2028,Uber “expects t have hundreds,if nt thusands,f its aircraft in the skies,” Gel tld Newsweek.
S what wuld Uber’s flying vehicles be like?
They are small,electric aircraft that take ff and land vertically(垂直地),and they give ff zer emissins (排放物) and are quiet enugh t perate in cities.
Just like an airplane,the vehicles will have fixed wings t help them glide.But while a helicpter has just ne big fixed rtr (旋翼),Uber’s vehicles will have multiple rtrs,which will help increase efficiency (效率) while reducing emissins and nise.
Because f these fixed wings and multiple rtrs,Uber’s flying taxis “shuld be quieter and safer than a helicpter”,reprted ABC News.
Hwever,the service still has a lng way t g befre it’s ready t accept passengers.Fr example,t avid any ptential accidents,Uber is wrking with NASA t study air traffic cntrl prblems assciated with lw flying aircraft.But just as an expert cmmented,“This prgramme is revlutinary and future-riented (面向未来的).”
