as u.s. airlines and boeing are trying to calm concern about the boeing 737 max 8, a second flight attendant union is asking for the plane to be grounded after the crash. moments ago the european union suspended all flights of the boeing max planes. several countries have grounded the jets after all 157 people were killed on that ethiopian airlines flight. that is not the story, though, for us here in the united states. three major airlines continue to fly the max 8 jet, and then the max 9, as well. cnn's martin savage just spoke with a number of passengers as they landed there at hartsfield jackson in atlanta. so who do they have to say, martin? >> reporter: brooke, we talked to passengers, they had been on a max 8 that had flown from las vegas to atlanta. everyone that we spoke to said they were well aware of the two tragic and fatal plane crashes.
