Story Structure — 5 Plot Phases
The Dangerous Assignment
A high-altitude pilot is selected despite earlier flight difficulties and questionable judgment. The experimental Y-13 begins its mission under growing concern.
Key Events
-
Pilot Selection Dispute — A commander questions whether his brother should pilot the high-altitude Y-13.
Location: Air Force Space Command
-
Technical Briefing — The pilot is checked out and briefed before the experimental flight. Characters: Dr. Paul von Essen
Location: Air Force Space Command
-
Earlier Flight Difficulties — The pilot previously experienced difficulties while flying the Y-12 in the ionosphere.
Location: Ionosphere
-
Unauthorized Landing Delay — After landing, the pilot sees his girlfriend instead of filing the required flight report.
Location: Air Force facility
-
Y-13 Begins Ascent — The rocket-powered aircraft begins its high-altitude flight.
Location: Launch area
Beyond the Flight Plan
The pilot ignores the planned descent and uses emergency thrust to climb far beyond the intended altitude. The aircraft encounters an unknown cloud, forcing an ejection.
Key Events
-
Pilot Ignores Descent — At 600,000 feet, the pilot continues climbing and fires the emergency boost.
Location: Upper atmosphere
-
Extreme Altitude Reached — The aircraft reaches 1,320,000 feet and passes through a dense unknown cloud.
Location: Upper atmosphere
-
Emergency Ejection — The pilot loses control and ejects from the aircraft.
Location: Upper atmosphere
Blood and Meteor Dust
The wreckage is covered by an impenetrable substance as violent killings spread near the crash site. Investigators connect the victims to the aircraft through strange particles and equipment.
Key Events
-
Wreckage Investigation — Investigators find the wreckage, while the escape and braking systems appear to have worked perfectly.
Location: South of Alvarado, New Mexico
-
Cosmic Encrustation Found — Unknown rock-like material completely encases parts of the aircraft fuselage.
Location: Crash site
-
Blood Bank Attack — A wheezing creature kills a nurse and drinks vast quantities of blood.
Location: Alameda New Mexico State Blood Bank
-
Cattle Slaughter Reported — A newspaper reports brutal cattle killings near the aircraft crash site.
Location: Farm near the crash site
-
Matching Wounds Discovered — The nurse and cattle have similar wounds, shiny specks, and a lead from the Y-13 is found.
Location: New Mexico State Blood Bank
-
Meteor Dust Identified — Tests identify the shiny particles as meteor dust without atmospheric damage. Characters: Dr. Paul von Essen
Location: Aviation Medicine
The Cosmic Protection
Scientific tests reveal that the encrustation protects some metal while destroying uncovered material. This evidence leads to a theory about the pilot's altered body and need for oxygen-rich blood.
Key Events
-
Cosmic Protection Theory — The encrusted metal remains intact, while uncovered metal becomes brittle and carbon-like. Characters: Dr. Paul von Essen
Location: Aviation Medicine
-
Survival Transformation Theory — The investigation proposes that the cockpit coating protected the pilot but altered his metabolism.
Location: Investigation area
-
Helmet Confirms Identity — A coated helmet found with the latest victim confirms the investigator's theory about the creature.
Location: Abandoned car
A Last Breath of Humanity
The creature breaks into the investigation building and is guided toward a high-altitude chamber. The chamber restores part of the pilot's humanity, but he dies after recalling his ambition.
Key Events
-
Creature Enters Headquarters — The encrusted creature crashes through a window as officials contact Washington. Characters: Dr. Paul von Essen
Location: Investigation building
-
High Altitude Chamber Plan — The chamber is opened while directions are broadcast to guide the creature through the corridors. Characters: Dr. Paul von Essen
Location: Aviation Medicine building
-
Chamber Tragedy — At 38,000 feet, the pilot breathes more easily, briefly regains humanity, and then dies. Characters: Dr. Paul von Essen
Location: High-altitude testing chamber
-
Final Confession — The dying pilot says he wanted to be the first man into space before collapsing.
Location: High-altitude testing chamber
The first pilot to leave Earth's atmosphere lands, then vanishes; but something with a craving for blood prowls the countryside...
