De acordo com a novela oficial , foi para economizar energia .
Vale a pena notar que Vader nem sequer considerou a possibilidade de que estes planos vitais teriam sido confiados a um mero droide, adivinhando que o pod simplesmente continha " fitas ". Em circunstâncias normais, os droides são relativamente estúpidos e não têm nenhum senso de autonomia, então deve ter sido uma surpresa descobrir que eles haviam sido enganados por uma torradeira:Moving to the man’s position, the Captain stared into the circular viewscreen and saw a tiny dot dropping away toward the fiery world below. “There goes another pod, sir. Instructions?” The officer’s hand hovered over a computerized energy battery.
Casually, confident in the firepower and total control under his command, the Captain studied the nearby readouts monitoring the pod. All of them read blank.
“Hold your fire, Lieutenant Hija. Instruments show no life forms aboard. The pod’s release mechanism must have short-circuited or received a false instruction. Don’t waste your power.” He turned away, to listen with satisfaction to the reports of captured men and material coming from the rebel ship.
Vader appeared thoughtful. “It could have been a malfunctioning pod,” he mused, “that might also have contained the tapes. Tapes are not life forms. In all probability any native finding them would be ignorant of their importance and would likely clear them for his own use. Still …
“Send down a detachment to retrieve them, or to make certain they are not in the pod,” he finally ordered the Commander and attentive officer. “Be as subtle as possible; there is no need to attract attention, even on this miserable outpost world.”
Na nova história de Star Wars De um certo ponto de vista: o Sith do trabalho de dados , aprendemos que promoções entre Os comandantes de artilharia imperiais estavam ligados a "proporções de morte", e que atirar em cima de uma cápsula registrando-se como vazia contaria contra sua pontuação mesmo se a atingissem perfeitamente.
Well, this was interesting. “Are we trying to conserve lasers now?” He ignored my sarcasm, but his face turned red. “The sensors detected no life-forms aboard. I thought…um…we wouldn’t have been scored with a kill…so…”
Of course; now his actions made perfect sense. Annoyed with rebel propaganda that showed Imperials to be poor shots—frankly, the stormtroopers could do with more targeting drills—fleet bureaucrats had issued a new policy that tied gunnery officers’ promotions to their kill ratios. Shots fired at unoccupied escape pods would indeed be considered wasted. I thought this was a terrible idea at the time. The new policy would encourage some ambitious gunners to aim for rebel pilots in disabled vessels rather than dangerous, armed drones. But the brass never asked for my opinion.
