Twelve clues contain a misprint of one letter in the definition, the corrections spelling out an experimental mission. The immediate outcome is shown by removals, read in normal grid order, from eight across answers. The name of the delivery agent appears in a cluster of four cells, and must be highlighted along with symbolic representations of two further items which became apparent in the aftermath.
