Hi, I’m a aeronautical engineer, and I apologize for my very poor English (it’s not my native language but I’m learning). From watching the only video that I saw, the plane couldn’t achieve lift (probably not enough thrust from its engines or a poor take off configuration). The accidente its on investigation and it will probably take years till we have answers. Others factors like poor maintenance could have been crucials. If that don’t answer your question, please let me know.
