American Airlines CEO Robert Isom has stated that the National Transportation Safety Board ( NTSB) will be the only source of information surrounding the terrible mid-air accident involving American Airlines Flight 5342. On Wednesday night, a US Army Black Hawk helicopter and a small American Airlines plane operated by PSA Airlines crashed, killing all 67 people on board. Isom highlighted that while the investigation is ongoing, the NTSB’s conclusions will be conclusive.
