11、h a domestic flight, at least at some major U.S. airports with increasingly massive security lines.Americans are willing to tolerate time-consuming security protocols in return for increased safety. The crash of Egypt Air Flight 804, which terrorists may have downed over the Mediterranean Sea, provi

12、des another tragic reminder of why. But demanding too much of air travelers or providing too little security in return undermines public support for the process. And it should: Wasted time is a drag on Americans economic and private lives, not to mention infuriating.Last year, the Transportation Sec

13、urity Administration(TSA) found in a secret check that undercover investigators were able to sneak weapons both fake and real past airport security nearly every time they tried. Enhanced security measures since then, combined with a rise in airline travel due to the improving economy and low oil pri

14、ces, have resulted in long waits at major airports such as Chicagos OHare International.

15、ow rushing to get new screeners on the line. Part of the issue is that airports have only so much room for screening lanes.

16、 TSA could take that would not require remodeling airports or rushing to hire: Enroll more people in the PreCheck program. PreCheck is supposed to be a win-win for travelers and the TSA. Passengers who pass a background check are eligible to use expedited screening lanes. This allows the TSA to focu

17、s on travelers who are higher risk, saving time for everyone involved. TSA wants to enroll 25 million people in PreCheck.It has not gotten anywhere close to that, and one big reason is sticker shock: Passengers must pay $85 every five years to process their background checks. Since the beginning, th

18、is price tag has been PreChecks fatal flaw. Upcoming reforms might bring the price to a more reasonable level. But Congress should look into doing so directly, by helping to finance PreCheck enrollment or to cut costs in other ways.The TSA cannot continue diverting resources into underused PreCheck

19、lanes while most of the traveling public suffers in unnecessary lines. It is long past time to make the program work.21.

23、monarch, in 1897. Star watchers were among the most esteemed members of Hawaiian society. Sadly, all is not well with astronomy in Hawaii today. Protests have erupted over construction of the Thirty Meter Telescope (TMT), a giant observatory that promises to revolutionize humanitys view of the cosmo

24、s.At issue is the TMTs planned location on Mauna Kea, a dormant volcano worshiped by some Hawaiians as the piko, that connects the Hawaiian Islands to the heavens. But Mauna Kea is also home to some of the worlds most powerful telescopes. Rested in the Pacific Ocean, Mauna Keas peak rises above the

25、bulk of our planets dense atmosphere, where conditions allow telescopes to obtain images of unsurpassed clarity.Opposition to telescopes on Mauna Kea is nothing new. A small but vocal group of Hawaiians and environmentalists have long viewed their presence as disrespect far sacred land and a painful

26、 reminder of the occupation of what was once a sovereign nation.Some blame for the current controversy belongs to astronomers. In their eagerness to build bigger telescopes, they forgot that science is not the only way of understanding the world. They did not always prioritize the protection of Maun

30、the telescopes visibility around the island and to avoid archaeological and environmental impact. To limit the number of telescopes on Mauna Kea, old ones will be removed at the end of their lifetimes and their sites returned to a natural state. There is no reason why everyone cannot be welcomed on
