We're adding a triple sign-off for all work done on the launch pad, on flight components, and flight critical GSE. You have a technician, a responsible engineer, and then quality assurance will sign the final, record all information, and take photographs of all the work that was done, and then make sure that all information is put into our quality assurance database, which is reviewed prior to launch.
