Boeing delivered nearly 39 percent fewer aircraft in the first half of this year compared to the same period last year. The group supplied a total of 239 aircraft. The American aircraft maker announced this on Tuesday. Boeing has been in heavy weather for months due to two plane crashes involving the Boeing 737 MAX aircraft. A total of 346 people were killed in aircraft crashes with the Boeing aircraft in Indonesia and Ethiopia. The 737 MAX aircraft are on the ground worldwide since the crash in Ethiopia in March. Prohibitions were imposed after the two fatal aircraft accidents. Both crashes were caused by technical problems with the steering system which was ‘too smart’ to trust the pilots. Due to falling deliveries, the company may for the first time in eight years make fewer deliveries than the European competitor Airbus. According to Reuters news agency, Airbus deliveries have risen by 28 percent in the first half of the year. This might be enough to beat Boeing.
