Loon on the Moon The cadets are on assignment to dig for Helium-3 (the source of their rocket fuel) under the watchful eye of Loon, the eccentric, beloved senior Chief Engineer of Stardust Bay's Lunar Campus. Now about 250, he's been working up there since the school first created its Moon base. When Eagle makes a careless mistake, an angry Vulture blames the elder rocket and demands his retirement. At the big farewell party, all the cadets and teachers show up to honor him. But when a moonquake unexpectedly causes a panic, Loon's experience and relaxed demeanor save the day: unlike earthquakes, which are over quickly, he knows that moonquakes can last for up to 10 minutes. His retirement is overturned by popular demand, and the party becomes a celebration for Loon's next 100 years on the Moon!
