Old age is like a plane flying through a storm. Once you’re aboard, there’s nothing you can do.

The simile frames aging as an irreversible passage: once “aboard,” one must endure turbulence rather than control it. The “storm” suggests physical decline, uncertainty, and the loss of agency that can accompany later life, while the airplane implies modern speed and inevitability—aging carries you forward regardless of will. The line’s bluntness also hints at a stoic, unsentimental attitude: the appropriate response is not denial but endurance and adaptation. Read this way, the quote functions less as despair than as a recognition of limits—an invitation to focus on what can still be chosen (attitude, preparation, companionship) even when the larger trajectory cannot be altered.
