An explosion in the cabin is believed to have caused this breach in the fuselage of TAM Airlines Fokker100 PT-MRK on 9 July. The aircraft was on a regional flight from Sao Jose dos Campos to Sao Paulo, Brazil, with 60 people on board. One passenger is known to have been blown out of the hole. The captain, who made an emergency recovery to Sao Paulo Conghonas Airport, says: "Fortunately, we were not flying at a high altitude." Evidence of heat damage shows a chemical explosion could have been involved.
