Emergency response personnel contain possible hazardous materials or oils that may have spilled during an aircraft crash exercise at Joint Base Langley-Eustis, Virginia, July 17, 2018. The exercise allowed Wing Inspection Team members to evaluate the plans, processes and training that each unit has conducted to help commanders at all levels adjust training, provide additional resources where there is a need or develop a team to revise plans and processes, if need be.
