A Delta Air Lines flight aborted its landing at Boston Logan International Airport on Saturday after coming within an estimated 300 feet of an American Airlines jet departing from an intersecting runway. The aircraft, carrying 129 passengers and six crew, executed a go-around and landed safely without reported injuries. The Federal Aviation Administration has opened an investigation into the near-miss, which a former Boeing safety engineer described as a “significant incident” given that both flight crews were professional operators.

In Memphis, Tennessee, a ground equipment vehicle struck a Southwest Airlines plane on Sunday as passengers were boarding. The airline confirmed that Flight 4013 was taken out of service following the contact; no injuries were reported. Passengers were transferred to an alternate aircraft and departed nearly four hours behind schedule. Southwest stated the event would be examined through its Safety Management System, while the airport authority described it as an isolated matter.

A separate in-flight disturbance occurred on an American Airlines flight approaching Philadelphia on Sunday. Air traffic control audio, reviewed by US media, captured the pilot reporting that a passenger had bitten a fellow traveller and was “trying to fight everybody.” The pilot requested an emergency medical crew as a precaution. American Airlines later characterised the individual’s behaviour as a “medical emergency” and said a medical professional on board assisted. It did not confirm whether law enforcement met the aircraft upon arrival.

The Boston incident precedes a Capitol Hill hearing scheduled for Tuesday, where the Senate Commerce Subcommittee on Aviation, Space, and Innovation will examine near-misses and runway incursions at US airports. All three events remain under investigation by the relevant authorities, and no serious physical injuries have been confirmed in any of the cases.
