Being can't catch a break. After their 737 Max finally took back to the skies after 2 years anothe problem is on the table. On the wekend there were 2 problem with 777 with Pratt&Whitney engines which caught fire and both planes had to make emergency landing. After this Boeing and FAA advise to ground these types of 777 until problem is solved. This can have another negative effect on their share price. (Sider, Wall Street Jounral)
