Metalstorm threw a small beacon, capable of a human for carrying, into the building lightly, so that maybe the Doctor or C.C. or anyone else who knew what was going on could summon him. "I'm off to find a new form!" He shouted, and transformed, not waiting for their response. His alien jet form took off into the sky, clearly visible on human radar. He had also went almost immediately to mach speeds, shattering the schools windows, and definitely waking people up, even knocking those closer to him over.. He flew near to one of their military bases, and started looking for a local vehicle to scan. After a few minutes, he saw what appeared to be an old, unused jet. He flew low over it, only a few meters, and as soon as he passed directly over, he took it's form. Now, if one was color-blind, he would blend in perfectly with the other Britannian fighter jets (not that any were used).
