Illusions of Lift
A pilot can create an indication of lift on certain uncompensated instruments by entering a climb by pulling back on the stick (hence “stick thermal”). This is not true lift, in that the energy to climb is being converted from decreasing airspeed, rather than being extracted from rising air. Inexperienced pilots can mistake this for actual lift.

“Swann was one of those men who, having long lived in the illusions of love, saw the well-being that they gave to many women heighten their happiness without evoking in these women any gratitude, any tenderness toward them; but in their child these men believe they feel an affection which, embodied in their very name, will make them outlast their death. When there was to no longer be a Charles Swann, there would still be a Mademoiselle Swann ... who would continue to love her departed father.”
—Marcel Proust (1871–1922)
“It is natural to indulge in the illusions of hope. We are apt to shut our eyes to that siren until she “allures” us to our death.”
—Gertrude Stein (1874–1946)
“This is essentially a People’s contest. On the side of the Union, it is a struggle for maintaining in the world, that form, and substance of government, whose leading object is, to elevate the condition of men—to lift artificial weights from all shoulders—to clear the paths of laudable pursuit for all—to afford all, an unfettered start, and a fair chance, in the race of life.”
—Abraham Lincoln (1809–1865)
