They were able to retask it during the execution of a preplanned mission ?

Pity the poor noun “task,” so frequently verbed and now subjected to prefixing as well. If adding “re-” to a verb generally means “to do it again,” shouldn’t retasking an aircraft mean reflying the mission rather than redefining it? Perhaps the aircraft should be detasked before retasking, or at least pretasked for retrotasking.
