Q: BOSTON, Massachusetts (CNN)  -- The operator of a trolley that rear-ended another trolley should have been able to see the other vehicle was stopped 480 feet ahead, a federal investigator said Monday. Passengers walk past firefighters at a Green Line station in Boston after the trolley collision Friday evening. The trolley driver has told investigators he was text messaging during Friday night's collision, which injured 20 people. The Massachusetts Bay Transportation Authority, which previously had banned operators from using cell phones and other portable devices, now has told employees to leave the devices at home while on duty, National Transportation Safety Board member Debbie Hersman said Monday. Hersman also noted investigators have determined that the operator may have missed some crucial indications of a stopped trolley ahead on the tracks.  Watch new transit rule on cell phones » . "There were several signals -- two green signals, a yellow signal and a red signal -- coming out of the station, and the point of collision occurred 80 feet past that red signal," Hersman said. "We did a site-distance test, and we know that the operator had the ability to see the trolley stopped in front of him 480 feet in advance of the collision." Boston officials said over the weekend that the trolley operator was using his cell phone. Numerous media outlets, including CNN's Boston affiliates, have identified the driver as 24-year-old Aiden Quinn. "The operator of the striking train was interviewed at the hospital by two detectives," said MBTA general manager Daniel Grabauskas. "He admitted that he was texting at the time of the accident." The operator told detectives that, when he looked up, "it was too late as he applied the brake and the train struck the other trolley," Grabauskas said. He described himself as "outraged." "We have reinforced for a number of years that the use of cell phones or any other kinds of electronic devices while operating a train or a bus is absolutely prohibited," Grabauskas said. Though the investigation is ongoing, he said, the two-year employee will be fired if his version of events is confirmed. None of the injuries was considered life-threatening, the MBTA said. The collision happened at 7:18 p.m. ET Friday as the Green Line trains were traveling between the Park Street and Government Center stations in downtown Boston. Both trains were traveling westbound when one train rear-ended the second, an MBTA official said. A train operator also was text messaging last year in a California train crash that killed 25 people. CNN's Rob Frehse and Gary Bender contributed to this report.

Q: (CNN) -- Even a presidential campaign's airplane troubles can get partisan in an election year. Aviation incidents involving President Barack Obama and Ann Romney, wife of Republican presidential candidate Mitt Romney, have inspired hundreds of supporters commenting at CNN.com to connect those events to the candidates' political positions. When the Air Force One pilot aborted his first landing in Toledo, Ohio, due to weather on Wednesday, commenters were quick to jump on Obama. "See, Barack Obama can't even land a plane correctly," wrote a commenter whose handle is TheOtherBob. "He was probably checking the polls - thinks he has Ohio in the bag - no need to land," wrote another commenter. "He was distracted, since he was busy adjusting gas prices over his smart phone," wrote another commenter. Ann Romney's smoke-filled plane . Ann Romney couldn't catch a break, either. Her airplane cabin filling up with smoke due to an electrical problem was no laughing matter, but commenters quickly took aim at her husband and his response. Mitt Romney talked about not being able to open the airplane's windows in flight. (New York Times writer Ashley Parker, who wrote the presidential pool report mentioning the comments, declined to comment on his remarks, referring CNN to a New York magazine piece where she made it clear that Romney was joking.) "Maybe if Romney hadn't started the outsourcing trend, that plane would have been built and maintained better by hardworking 47%ers," wrote one commenter. "Firefighters came to the rescue, paramedics were there on time and the police took special care of your security. We are the 47% your husband scorns," wrote commenter Kweso. Reminders of the actual flying conditions . Enough with the political bickering, suggested some commenters. "The hate thrown out at the Romneys (and at President Obama) is just plain absurd," wrote commenter jolivier23. On Romney's flight: "CAN YOU PEOPLE STOP WITH THIS CHARADE. Can you just be happy that the everyone was safe and no one was injured," wrote one commenter. "What is wrong with you people? Why are you making this a political issue? I am just glad nobody was hurt. " On Obama's flight: "This incident with the President was just routine turbulence which is something that you really can't do anything about in the first place," wrote one commenter. "If the one of the best pilots (and co-pilots) in the U.S. Air Force aborts a landing you know the conditions were hairy," wrote daehttub2000. Perhaps remembering a line from that esteemed television show "Hill Street Blues," he wrote, "Let's be careful out there." Many of us have stories of grabbing a complete stranger or picking airline pretzels out of our hair after a particularly bad bout of turbulence. Do you have any stories to share?
