Hawker Beechcraft and the state of Kansas reached an ­agreement late last month that will keep the airframer in Wichita for at least the next decade. In return for HBC maintaining its current ­production lines and ­retaining at least 4,000 jobs over the next 10 years, the state offered a $40 million incentive package that includes $30 million over the next five years for equipment ­purchases, product development or building costs and another $10 million allocated for tuition reimbursement and training for company employees at any state institution. In addition, the city of Wichita and Sedgwick County each agreed to provide $2.5 ­million over the next five years.
