Boeing’s post-crash business slump may be coming to an end. The plane maker said Thursday that it’s in negotiations with several customers interested in buying the 737 Max jet, as it tries to rebuild trust in the plane and its own reputation after two Max crashes that killed 346 people. At the Paris Air Show this week, Boeing won its first endorsement of the 737 since an Ethiopian Airlines crash in March and a Lion Air crash in October in Indonesia.
