Angela could have carried him. It would have been fairly easy to do as long as he didn't bring to many of the heavy weapons with him, but he apparently wanted to bring the entire armory. When he got into the car she leapt into the air had to fly high enough that no one on the group would take notice of her. That meant she had a hard time seeing his car below but once they were out of the town it would be easier and she could fly a little lower.<br/><br/>Being in the air allowed her to see when the backup for the police station showed up. Several military vehicles and other police cruisers along with a few dozen men. They had left just in time.<br/><br/>Angela flew ahead of John and landed on the side of the country road right outside of town. As her feet touched the ground her wings disappeared from view and she waited for him to pick her up. If they weren't going fly together there was no reason for her to be in the air.
