This tragedy unfortunately may be but the latest in Boeing's recent string of malfunctions. Pressure from its rival, Airbus, has likely given the company financial incentive to cut corners, and travelers are right to remain distrustful. Although it may be too soon to know what caused the crash, Boeing needs to prove that it values safety over profit.
The 737-800 that crashed is one of the safest and most widely used aircraft in the world. There's been no indication of foul play or negligence, and the investigation must be led with facts. Chinese authorities are rightfully using caution in the face of the ongoing investigation and will share details when the root cause of the crash is determined.
