The Haunted Hangar: Sky Scouts/Air Mystery series #3

In Short

The Haunted Hangar is a lighthearted 1932 juvenile air-mystery novel that follows teenage aviation enthusiasts Larry Turner, Dick Summers, and Sandy Maclaren—collectively known as the Sky Patrol. When a priceless set of thirty matched Hindu jewels, the Everdail Emeralds, vanishes during a flight off the Atlantic coast, the boys team up with veteran pilot Jeff to investigate. Amid sabotaged aircraft, dark fogs, swindlers, and a "ghost" lurking around an old seaside estate, the trio uses aerial pursuit and clever deduction to crack the puzzle. It survives as a charming period artifact of early civil aviation and classic youth-detective fiction.

The Story

The adventure opens high in the air as sixteen-year-old Larry Turner, fifteen-year-old Dick Summers, and thirteen-year-old "Suspicious Sandy" Maclaren take a flight with Jeff, a former World War I flying ace. When the engine cuts out, Jeff makes a forced landing at an abandoned estate on Long Island Sound once owned by aviation magnate Atley Everdail. Jeff reveals that he has been recruited by Everdail to help safeguard the Everdail Emeralds—a priceless set of thirty matched gems given to an ancestor by a wealthy Hindu Nabob—which are targeted for destruction or theft by unknown conspirators.

The mystery deepens when a seaplane and a luxury yacht named the Tramp meet offshore. Inside a dense bank of fog, a mysterious figure parachutes into a swamp, dropping a life preserver into the water. Joining the search, the Sky Patrol recovers chewing gum containing thirty fake emeralds hidden near a submerged seaplane, while the real gems remain missing. Sandy suspects that Jeff himself might be in on the plot, while the group navigates a web of deceptive figures, including Mrs. Everdail's suspicious maid Mimi, an enigmatic detective named Mr. Whiteside, and various estate workers.

Throughout the investigation, Larry receives practical flying instruction from Jeff and another pilot, Tommy Larsen, eventually mastering controls, dual flights, and solos despite mysterious "hoodoos" and sabotage affecting their aircraft. Meanwhile, Dick and Sandy form a dedicated "ground crew" to guard the estate's old hangar, which local rumor claims is haunted by a nocturnal ghost manipulating fuel supplies and aircraft.

Following a series of aerial chases, zig-zag tracking maneuvers across Long Island Sound, and close encounters in storm-tossed skies, the villainous mastermind behind the plot perishes when his plane crashes into a tree during a desperate getaway. Yet even with the suspects caught and every life preserver on the yacht ripped open, the genuine emeralds are nowhere to be found.

Sandy realizes that the real gems must have been hidden in plain sight aboard the yacht's refrigeration plant. The boys stage a fake fire alarm on board the Tramp, using colored smoke powder in the galley to panic the thief. The yacht's chef rushes into the kitchen and pulls two ice trays from the freezer, revealing green ice cubes hiding the real Everdail Emeralds. With the chef's confession and the jewels restored to their rightful owner, the Sky Patrol earns reward checks and pledges to join Jeff on future flying adventures.

How It Unfolds

Engine trouble in the skies While flying over a seaside estate, pilot Jeff cuts the engine and glides into an abandoned air strip, claiming a dead stick. Suspicious Sandy notices Jeff cut the ignition deliberately, leading Jeff to reveal a letter from his war buddy Atley Everdail regarding the threatened Everdail Emeralds.

Mystery over the ocean The Sky Patrol flies out over Long Island Sound to coordinate with the yacht Tramp and a meeting hydroplane. As a rolling fog banks over the water, an unknown parachutist leaps from a seaplane into the swamp, setting off a race for missing jewels.

Clues in the swamp Investigating the wreckage of a submerged seaplane, Larry and Jeff retrieve chunks of fresh chewing gum hidden near the craft. Inside the gum, Sandy discovers thirty fake emeralds, proving that an elaborate shell game is underway to conceal the genuine stones.

Flight school and sabotage Larry takes up dual-control flight lessons with Jeff and Tommy Larsen, learning airspeed, taxiing, and engine safety while Sandy and Dick investigate the estate grounds. Mid-flight, a mysterious mechanical failure strikes their aircraft, forcing the boys to handle an emergency control job.

Traps and night chases The boys attempt to bait the thief using a modified life preserver as a decoy, leading to an intense night flight across the Sound. Using a zig-zag aerial search pattern guided by running lights and flash signals, Larry trails a speeding hydroplane toward the Connecticut shore.

The haunted hangar Dick and Sandy act as a "ground crew," staying behind to stake out the estate's dark hangar where a ghost has been spotted moving equipment. Sandy sneaks into the fuselage of an amphibian plane, stowing away just as Jeff takes off into a gathering thunderstorm.

The green ice trap After the chief conspirator crashes into a tree during a stormy pursuit, the real emeralds remain missing until Sandy deduces their location aboard the yacht. By setting off smoke pots to simulate a shipboard fire, the boys catch the chef retrieving green-dyed ice cubes containing the hidden gems from the galley freezer.

In Its Own Voice

"Steady, all! Engine's quit and left us with a dead stick! No danger." --- Pilot Jeff reassures his young passengers as he glides toward an abandoned private air strip.

"That engine didn't die. I saw what Jeff did. He was as quick as a cat--but he didn't fool me." --- Young Sandy Maclaren immediately suspects hidden motives behind their unexpected landing.

"They contained--green ice!" --- The Sky Patrol catches the thief red-handed in the yacht's galley during the staged fire alarm.

What It's Really About

At its core, The Haunted Hangar explores the transition from skepticism to structured critical thinking among young people. Sandy Maclaren begins the story as overly suspicious, distrusting everyone from his flight instructor to estate workers based purely on instinct. Over the course of the investigation, he learns to channel his doubts into methodical observation, piecing together mechanical, chemical, and physical clues rather than jumping to wild accusations.

The novel also contrasts early 20th-century technology—refrigeration, radio equipment, and open-cockpit aviation—with older forms of crime and greed. It asks whether modern discipline, technical education, and clear-headed teamwork can outmatch trickery and superstition in a rapidly changing world.
