Cassa 212 aircraft Allegedly Fall Due to Hurricane Nesat

Jakarta - Until now the cause of the crash Cassa 212-200 PK-TLF-owned PT Buana Nusantara Air (NBA) in the limestone mountains of the Southeast Aceh is still unknown. Allegedly plane carrying 18 people crashed due to storm Nesat.

The analysis was presented expert tropical meteorology and Implementation Agency for the Assessment of Technology (BPPT) Tri Handoko Dr. Seto in an email to AFP on Thursday (29/09/2011).

According to Tri, 212 Cassa planes typically fly at an altitude of 7,000 to 8000 feet for a commercial airline routes. "At that altitude, wind speed is currently in the middle to the northern part of Sumatra is very high, about 20-40 knots. This is the result of tropical cyclones Nesat is happening in the northern area of Indonesia," said Tri.
