ലോസ്ആഞ്ചല്‍സില്‍ നിന്നു ന്യൂയോര്‍ക്കിലേയ്ക്കു പുറപ്പെട്ട അമേരിക്കന്‍ എയര്‍ലൈന്‍സിന്റെ വിമാനത്തിനു യുദ്ധ വിമാനങ്ങളുടെ അകമ്പടിയോടെ ലാന്‍ഡിംഗ്. വിമാനത്തിലെ മൂന്നു യാത്രക്കാര്‍ ബാത്ത്‌റൂമിനുള്ളില്‍ കയറിയശേഷം ഏറെ സമയം കഴിഞ്ഞിട്ടും പുറത്തിറങ്ങാത്തതിനെത്തുടര്‍ന്നാണ് വിമാനത്തെ യുദ്ധവിമാനങ്ങള്‍ അനുഗമിച്ചത്.

സെപ്റ്റംബര്‍ 11 ആക്രമണത്തിന്റെ പത്താം വാര്‍ഷികത്തിലാണ് സംഭവം. അതേസമയം, സംഭവത്തിനു തീവ്രവാദ സ്വഭാവമില്ലെന്ന് യുഎസ് അധികൃതര്‍ പറഞ്ഞു. രണ്ടു എഫ്- 16 ജെറ്റ് വിമാനങ്ങളുടെ അകമ്പടിയോടെയാണ് യാത്രാവിമാനം JFK വിമാനത്താവളത്തില്‍ ഇറങ്ങിയത്.
ഈ യാത്രക്കാരെക്കുറിച്ചും ഇവരുടെ ഉദ്ദേശത്തേക്കുറിച്ചും കൂടുതല്‍ വിവരങ്ങള്‍ അധികൃതര്‍ വെളിപ്പെടുത്തിയിട്ടില്ല. 9/11 വാര്‍ഷികത്തില്‍ ഭീകരാക്രമണം നടത്തുമെന്നു തീവ്രവാദികളുടെ ഭീഷണിയുണ്ടായിരുന്നു. ഇതിന്റെ പശ്ചാത്തലത്തിലാണ് യാത്രാവിമാനത്തെ അനുഗമിക്കാന്‍ യുദ്ധവിമാനങ്ങള്‍ക്കു നിര്‍ദ്ദേശംനല്‍കിയത്.

Fighter jets were scrambled to escort two commercial flights into New York City and Detroit "out of an abundance of caution" after crews reported suspicious activity on the 10th anniversary of the Sept. 11 terrorist attacks, officials said.

The bathroom use by some passengers aroused the suspicion Sunday, but all were released after being questioned by authorities on the ground.

On an American Airlines flight from Los Angeles, three passengers who made repeated trips to the bathroom were cleared after the plane safely landed at New York's Kennedy Airport.

Earlier, on a Denver-to-Detroit Frontier Airlines flight, the crew reported that two people were spending "an extraordinarily long time" in a bathroom, Frontier spokesman Peter Kowalchuck said. Police detained three passengers at Detroit's Metropolitan Airport, but they also were eventually released.

Asked late Sunday if authorities may have overreacted, airport spokesman Scott Wintner said the airport's response wasn't unusual and the same steps would have been taken any other day of the year.

"Regardless of why it was triggered, whenever we get a radio call of a security problem on board, our response is the same one we would have had yesterday, tomorrow," Wintner said.

"We always react as if it's the end of the world," he added. "If it isn't, so be it."

New York, in particular, has been in a heightened state of security after federal officials received a credible but uncorroborated tip of a car bomb plot on the 9/11 anniversary in either New York or Washington.

American Airlines spokesman Tim Smith said the plane's captain never declared a security threat and never asked for law enforcement help. A "security concern" was brought to the airline's attention and the crew used "normal procedures" to assess the circumstances, he said. The plane landed as planned.

"In our eyes, it's a big nothing," Smith added.

Still, the North American Aerospace Defense Command scrambled two F-16 fighter jets to shadow American Airlines Flight 34 until it landed safely at 4:10 p.m., the Transportation Security Administration said in a statement.

On the flight, the three passengers made repeated trips to the bathroom and some thought they were using hand signals to communicate, a law enforcement official said. The official was not authorized to speak publicly and spoke to The Associated Press on condition of anonymity.

Two of the men were Israeli and one was Russian, the official said, adding that the three were cleared and sent on their way.

FBI spokesman J. Peter Donald said in a statement that the jets were sent to escort the flight "out of an abundance of caution." The FBI interviewed passengers and found "no nexus to terrorism," he said.

A similar scenario played out on Frontier Flight 623.

NORAD spokesman John Cornelio said the agency sent two F-16 jets to shadow the plane until it landed safely. The craft, with 116 passengers on board, landed without incident at 3:30 p.m. EDT and taxied to a pad away from the terminal, he said. The plane was searched, and authorities cleared the aircraft at 5:15 p.m. EDT, according to the TSA.

The flight originated in San Diego before stopping at Denver International Airport on its way to Detroit. The FBI said the jets shadowed the Detroit-bound plane for the same reason as in New York _ "out of an abundance of caution" _ and nothing was found during the search.

The three escorted off the Frontier flight in handcuffs included two men and a woman, passenger Ilona Hajdar of Charlotte, Mich., told The Associated Press.

Hajdar, 27, said she'd been asleep for most of the flight but realized there was a problem when the plane's bridge didn't extend at the gate. The plane then rolled to a remote spot on the airfield. After about a half hour, police SWAT boarded.

Fellow passenger Belinda Duggan of Troy, Mich., said the plane taxied by the gate and headed for a remote patch of tarmac.

"All of a sudden, a SWAT team went through and saying, `Please place your hands on the seat in front of you,'" Duggan said, adding that police had three dogs with them.

American Airlines passenger Steven Ciobo said nothing seemed amiss on the flight to New York until he saw police lights on the runway after the plane landed. He said airline workers told passengers to remain seated and that the authorities would meet the plane, and everyone was quiet as air marshals got on board and headed for the back.

"To be honest, I think it's reassuring that there was such a great response from the authorities," Ciobo said. "If there are people that are stupid enough to do those things on today of all days you wonder what's going on through their heads. But the fact that there were so many authorities there ... and that it all went so smoothly, I think they did a good job."

The jets intercepted the flight about 100 miles west of New York and shadowed it until it landed, Cornelio said.
