It’s really difficult to appreciate how thing will happen. The American Eagle regional flights in question use the Bombardier CRJ aircraft .They have a top operating temperature of 118 degrees, according to an American Airlines statement. On the other part, a fact is known: many deadly planes accident occur if the take off fails. The Bombardier CRJ700, CRJ900, and CRJ1000 , equipped with a General Electric CF34 engine, have 876 km/h top speed. Jets like Airbus and Boeing have bigger engines and less problems with the increase of temperature.
