Ukrainian Airlines Boeing crash is different than 737 Max saga, analyst says
A Ukrainian Boeing 737-800 crashed in Iran late Tuesday. The passenger jet went down moments after takeoff just outside Tehran, killing all 176 people on board. Both Iranian and Ukrainian officials say they suspect the crash was caused by mechanical issues. Carter Copeland, U.S. aerospace and defense analyst and founding partner of Melius Research, joins "Squawk Box" to discuss.
