American Airlines flight 590 from Tampa to Phoenix was preparing to take off this morning when tires on the right main gear burst. The pilots rejected takeoff at a speed of around 150 knots and vacated the runway at the last turnoff. A fire ensued, and after several minutes, fire crews responded. The flight was subsequently canceled.
According to American Airlines, "American Airlines flight 590 with service from Tampa (TPA) to Phoenix (PHX) experienced a mechanical issue on the runway prior to taking off. Customers safely deplaned and were bussed to the terminal. We never want to disrupt our customers’ travel plans and apologize for any inconvenience this may have caused."
Just a couple of days ago, a United Airlines flight lost a wheel on takeoff from Los Angeles.
