What a 2-Degree Error Teaches About Small Choices

On November 28, 1979, Air New Zealand Flight TE901, an 11-hour sightseeing flight from Auckland to Antarctica and back, carrying 237 passengers and 20 crew, crashed into the lower slopes of Mount Erebus, Antarctica, killing everyone on board.

The cause traced back to something remarkably small: the flight's navigation coordinates had been entered incorrectly by roughly 2 degrees of latitude, a difference amounting to about 27 miles off course. That deviation redirected the aircraft's path away from the flat sea ice of McMurdo Sound and directly toward the slopes of a 12,448-foot active volcano. In the near-whiteout Antarctic light, the pilots believed they remained over open water until it was too late to correct course.

A 0.56% deviation. Invisible in the moment. Catastrophic in its eventual consequence.

Why This Matters Beyond Aviation

Lives, much like flight paths, are composed of thousands of small decisions and minute directional adjustments. There's a common assumption that meaningful change requires dramatic, large-scale action. In reality, small course corrections, a percent or less, compound significantly over time and ultimately determine where a trajectory actually lands.

Current circumstances reflect countless earlier decisions, made consciously or unconsciously, that led directly to this exact point. That's not incidental. And the same ongoing capacity for choice remains available going forward: the real question is simply where the current trajectory is actually headed.

Imagining the Destination

Looking three, five, or ten years ahead, what would genuinely be hoped for? A few common answers: continued energy and freedom from burnout. Genuine joy through meaningful relationships and real rest. Financial stability that allows investment in an actual life rather than simple survival. Relationships that nurture rather than drain.

Small Realignments Worth Considering This Week

Health: Leaving work ten minutes earlier on a single afternoon for a walk outside, rather than staying to finish "just one more thing." Swapping one processed snack for a whole-food alternative, even once. Adding ten minutes of light movement or stretching before bed.

Financial: Redirecting even 1% of monthly income into a neglected savings or investment account. Reviewing one "feel good" purchase this week, pausing for a couple of days before buying, to genuinely assess whether it's actually wanted.

Relationships: Sending one genuinely thoughtful message to someone who hasn't been in touch recently. Asking one meaningful question during a family meal, "what was the best part of your week?", and genuinely listening to the answer. Choosing one conversation this week to give complete, undistracted attention, phone away, for even a couple of extra minutes.

Questions Worth Asking Directly

What small, roughly 1% adjustment, repeated consistently, would meaningfully shift the current trajectory for the better? Looking at finances five years from now, what would be worth having started this week specifically? In relationships, what modest shift in presence might matter considerably more in the long run than it seems to now? What does being genuinely "on course", healthy, connected, fulfilled, actually look like, and what subtle, sustained action keeps that course intact?

The Bottom Line

Without deliberate course correction, small deviations compound over time, carrying a trajectory further and further from where it was actually meant to land, a dynamic with genuinely catastrophic consequences in aviation, and genuinely significant ones in an ordinary life. As author Jim Rohn put it: "You cannot change your destination overnight, but you can change your direction overnight." Small, consistent shifts, made now, are what actually determine where things eventually land.

FAQ

How did such a small navigation error lead to such a catastrophic outcome? A roughly 2-degree deviation in flight coordinates, while numerically small, translated to a substantial 27-mile shift in the aircraft's actual path, redirecting it from open water directly toward a mountainous volcanic slope, with no visible warning until it was too late to correct.

Why do small, incremental changes matter more than dramatic, large-scale ones? Small changes are genuinely sustainable and tend to compound significantly over time, while dramatic changes are harder to maintain consistently. A small, consistent shift repeated over months or years often produces more lasting impact than a brief, intense effort.

How can someone identify which small change is worth making first? Reflecting on a desired future state, in health, finances, or relationships, and asking what small, currently achievable action would move meaningfully in that direction is a practical way to identify a genuine starting point.

Does changing direction require an immediate change in circumstances? No, as the quote from Jim Rohn suggests, direction can shift immediately even when the ultimate destination takes time to actually reach. A new trajectory, even from a small adjustment, changes where things eventually land over time.
