The missile would come from an anti-aircraft missile truck. I’d draw a small truck on one of the roads. The dog would dodge the missile because the alien is controlling the dog, and the alien is right there, secretly behind the Phantom pilot. The alien would be aware the missile was fired, and the alien wants the dog to keep flying the stealth plane…because in the story the alien is a master alien and he released his servant alien with the dogs help. And the master alien wants to let his servant alien escape by getting out in the field and signalling an alien apace ship to pick him up. The master alien sacrificed his chances of escape to make shure the distracting flight goes on long enough to work…meanwhile the dog is confused serving two masters, the Phantom pilot and the Master alien…Not to mention the Phantom pilot is the base commander and he ordered the missile truck sargent not to fire at the dog, but the guy did.
