Show HN: I'm an airline pilot – I built interactive graphs/globes of my flights(jameshard.ing)
Hey HN!

Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history.

This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all

If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

Love the destination matrix graph!

Damn this is soo cool im not even close to understrand all of it but its damn beautiful

Thanks for sharing. Folks who combine dual passions are a fountain of creativity.

just out of sick curiosity...something about flights with ill-behaved fliers. Ultimately, as one who does not work in the airline business and has flown often, how often are pilots and staff perturbed by customers?

I have only had very few incident with ill-behaved passengers, and none that escalated. Ill passengers is a different story, especially on longer flights! With no hard data to back this up, I think that medical emergencies are probably the most common form of abnormal event that we encounter.

Are you allowed to code while sitting in the cockpit but not actively flying?
jamesharding 6/27/2025|
On the long flights where we carry more than two pilots, we have allocated break time away from the cockpit. During those breaks, you can do whatever you like (sleep, watch a film, read a book, etc). I tend to try to sleep on the plane, but I always bring my laptop on trips to work on projects while downroute. Especially on west-coast trips with the 8 hours timezone change, I am usually awake at 2am which is great for being productive!

I am insanely productive when programming on flights without wifi, provided I've cached what I needed to beforehand. Something about it just works

I'm jealous - all that time sitting around to get something productive done, and I can't concentrate at all because I can't relax, the plane suddenly shakes and distracts me, and it feels like I'm lacking oxygen and am not thinking clearly. I remember trying to code some stupid iterator thing in Rust for a few hours and couldn't crack it. On the ground it was solved in like 10 minutes.

Your phone has a "do not disturb" feature

I'm jealous of them being able to be productive _on a plane_.

I can be productive on the ground no problem, but I'm mostly useless when I'm on a plane.

Ok, so no high-quality LLMs possible.

Very cool! Can you share any info on the 945min flight from back in June?
jamesharding 6/27/2025|
Thank you!

That flight was the return from Tokyo (RJTT) to London (EGLL). Due to the closure of Russian airspace, the outbound flight is longer than pre-war as we fly over Turkish airspace. Due to the wind patterns, it is almost always longer flying westbound, so we usually fly east both ways.

In this case, the weather at one of the ETOPS alternates that we use (Shemya, https://en.wikipedia.org/wiki/Eareckson_Air_Station) was out of limits, so we had to fly back Westbound with the associated headwind and longer flight time.

That destination matrix is something I’ve never seen before!

Super cool. Harkens back to days of Microsoft Flight Simulator

Very interesting visualisations! I'm surprised but at the same time not surprised at the apparent overlap between pilots and programmers.

Do you have a favourite/least favourite plane to fly, or are they all the same?

jamesharding 6/27/2025|
Slightly biased, but right now I am really enjoying the A350!

There are a few "gadgets" that really improve the QoL for pilots (moving map on the ground, camera in the tail for taxiing on the ground, much improved safety systems for situations like blocked pitot tubes, etc).

Cool. It would be neat to see velocity and altitude too.
