2 JetBlue planes collide on tarmac at Boston's Logan Airport

Two JetBlue Airways planes collided on the tarmac at Boston Logan International Airport early Thursday morning, damaging both planes but causing no reported injuries.

JetBlue Flight 777 was on a de-icing path before departing for Las Vegas when its left winglet struck the right horizontal stabilizer on the tail of JetBlue Flight 551, which was on an adjacent de-icing path en route to Orlando , the The Federal Aviation Administration said this in a statement.

The collision occurred at 6:40 a.m., the FAA said, adding that the agency would investigate. No passengers or crew were injured, JetBlue said in a statement.

“Safety is JetBlue's priority and we will work to determine how and why this incident occurred,” the company said.

The passengers were transferred to another plane, the company said, and both flights took off shortly after the incident, flight data showed.

JetBlue is embroiled in a messy deal to acquire Spirit Airlines. A federal judge in January blocked the $3.8 billion acquisition in an antitrust lawsuit brought by the Justice Department.

JetBlue is appealing the court's ruling, but has also told investors it could try to pull out of the deal.

Frequent close calls between aircraft in the United States, both on the tarmac and in the air, are a sign that an air safety system is increasingly under strain.

Last year, the FAA gave more than $100 million to a dozen airports to help prevent accidents after a series of near-collisions.

The agency issued a safety alert last March, saying that while data showed no increase in the number of incidents, “the potential severity of these events is concerning.”
