Over the course of six months the Boeing 737 Max 8 airplane model has been involved in two crashes, killing over 300 people in total. The similarities between the two crashes brought the model into question. Prof. Perrine Pepiot, mechanical and aerospace engineering, weighed in on the mechanics of the crashes based on preliminary data. The first of the two crashes, Lion Air Flight 610, occurred in Indonesia on October 29, 2018. The latter of the two, Ethiopian Airlines Flight 302, crashed on March 10 en route to Nairobi, Kenya.
