Cassie grew, pushing herself to her upper limits. She had to be careful, of course; they weren't alone on this runway and there was still wreckage everywhere. Some of this she nudged gently away with her feet, watching as she took steps that, even though she tried to tread lightly, shook what was on the ground. Okay so, even at her tallest, a 747 was still going to be huge and heavy, but she would probably be more useful at this size than at any other. The problem was getting to the plane. Right now it was veering closer to the city and there wasn't far Cassie could go without the risk of crushing anything underfoot. If the boys could get the plane to her, she could probably hold it steady long enough to get its passengers and flight crew out. "Try to get it back over here," she suggested, her voice booming. Cassie really hoped no other planes ignored grounding instructions or else she could get nailed in the face by an aircraft at any moment.
