Many air travelers were rattled after radar malfunctions delayed flights in and out of Logan International Airport on Monday, and combined with a recent report about a string of near collisions of planes on the runway, plane passengers – including students who rely on plane travel to get home – were left discouraged and jittery.

On Monday, flights arriving at and departing from Logan Airport were delayed up to eight hours because of radar malfunctions, according to travelers.

“I felt very uninformed,” said Jane Coulter, a junior in the College of Arts and Sciences and the College of Communication. “I wasn’t sure whether they were just saying it was because of the radar, or if there was some terrorist threat.”

Coulter, who was flying from Los Angeles and was scheduled to land at 8:30 p.m., arrived at Logan at 12:30 a.m. and said even the landing took longer than expected.

“People were just extremely fed up with the whole situation,” Coulter said. “They were screaming into phones wanting to change flights and yelling at the ground control.”

Coulter said part of the problem was that the airlines were not clearly informing passengers about the specifics.

In addition to Monday’s delays, Logan Airport has had 16 runway incursions and surface incidents over the last year, said Jim Peters, a spokesman for the Federal Aviation Administration’s Northeast regional office.

He said the most recent two incidents, including the latest on Oct. 4, are under current FAA investigation by a “tiger team.”

The team includes a FAA group of employees from different disciplines who will visit the facility for two to three days, Peters said.

“They will inspect everything from A to Z,” Peters said. “They will prepare a report with findings and recommendations for the airport.”

He said the FAA Northeast is working with the Massachusetts Port Authority to improve Logan runways and taxiways.

“There will be development of a brochure to identify hotspots, intersections on runways and taxiways where they have taken place,” Peters said, adding that the brochure will help educate pilots about these hotspots.

Peters said reports of the incursions characterize runway incident from levels A to D, A being the most serious. Only one of the incidents was characterized as an A, he said, while the rest have been Cs and Ds.

Peters said the only A-level incursion involved an Aer Lingus plane on June 9, but refused to explain any of the specific incidents. Heavy travel times like Thanksgiving and Christmas, he said, have nothing to do with these runway incursions or surface incidents.

MassPort declined to comment about Monday’s delays or the runway incursions and referred all questions to the FAA.

The FAA did not return phone calls about the radar problems on Monday.

CAS senior Petko Dimitrov said he is traveling to Sofia, Bulgaria this Friday and hopes there will not be any delays.

“I hope it won’t be delayed much, but it could be bad because of the recent problems,” Dimitrov said. “It’s normal for Boston.”

He said that last winter, his flight to Japan was delayed for three hours at Logan and the airline offered him only water during his wait.

“I know it can be bad waiting in the plane for one to two hours when they don’t supply anything,” Dimitrov said. “I sat two hours in a plane and then flew nine hours overseas. It’s not pleasant.”

Dimitrov said he plans to arrive two hours early for his international flight because the delays are hard to predict during the check-in process and are only apparent upon arriving at the departure gate.

The recent airline problems and delays have stirred many Boston University students to reconsider their Thanksgiving flight plans, which they often need to fit into a tight schedule.

“It’s extremely important that the airport is secure and also is running on schedule,” said Matthew Levison, a COM junior. He said he expects a balance between safety and efficiency, especially after the terrorist attacks of Sept. 11, 2001.

“Because of these new troubles, people like me who know and read about them will be expecting problems from the minute they get to Logan,” Levison said.

He said he does not want to miss class to sit in the airport and wait for a delayed flight.

Levison is traveling to Las Vegas to visit with his family for Thanksgiving and said he hopes his plane will not be delayed.

“Staying over an extra night means missing a whole day of classes,” Levison said. “Unfortunately, I don’t think all professors will take staying another night in Vegas as an acceptable excuse to miss class.”
