Plane flying commands first select the planes to fly the mission and their escorts, then equip them. They all fail when no planes to fly the mission can be equipped. Unlike bomb and paradrop, commands drop, fly, recon and sweep had an additional check that made them fail when no planes to fly the mission could be selected. Because "none selected" implies "none equipped", the additional check is redundant. Remove it. While there, break lines in calls of pln_sel() more tastefully.
