On June 9th, an Aer Lingus A330 and a US Airways 737 took off nearly simultaneously on intersecting runways at Boston's Logan airport. How close they came to colliding is still to be determined, but it was close enough that the EIN flight crew "contacted Logan's control tower just after the incident ''to report the close proximity of a second aircraft." The crew also called the airline's safety unit in Ireland, which reported it to Irish aviation authorities and to the NTSB."

The Globe reports that the control tower was very busy that night and understaffed, and that the controllers "got distracted and forgot about the task at hand and the error happened".
