Where they flew
Ten days of arrivals, drawn by the airplanes themselves.
Every track we could reconstruct, stacked on top of each other. Nobody drew
the bright line running in from the southwest - that is thousands of pilots flying the
published Fisk arrival by eye, over Ripon and up the railroad tracks.

The tide
Oshkosh fills up, then empties out.
For six days almost everything is inbound. Around Thu 23 the
balance tips and the airport starts giving the airplanes back -
Thu 23 alone saw 1,636 departures , the
single busiest movement day of the event in either direction.

The rhythm of a day
Arrivals come all day. Departures go early.
Summed across all ten days. The morning is when the field turns over -
the outbound rush is sharper and earlier than the inbound one, which trickles on
until dusk.

The exodus is concentrated.
The same grid for departures. Where arrivals spread across the whole week,
leaving happens in a few hard blocks - Thu 23 morning most of all,
peaking at 241 departures in a single hour.

Two runways, a taxiway, a grass strip, a helipad - and a lake.

The Fisk arrival stacks two corridors over the same
ground track: 90 knots at 1,800 feet, 135 knots at 2,300. 85% of the
traffic took the slow lane, 15% the fast one - and
96% held their assigned altitude.
The overflow
When Oshkosh fills, the neighbours take the rest.
Everything above counts Oshkosh only. This does not: it is the wider
regional picture, and it is the one part of this page built from a second, broader
dataset - every aircraft that came low anywhere in the area, not just the ones that
landed at Wittman. Most of the traffic at these fields never came to Oshkosh at all,
which is exactly why it was invisible until now.

How this was measured.
Arrivals and departures are derived from reconstructed ADS-B tracks: for every aircraft
we walk its full position history and record each transition between airborne and on the
ground at Wittman. 6,574,619 position reports from
5,054 aircraft went into it. Landing sites were found by
clustering touchdown positions, not from a chart.
Track data.
Historical ADS-B traces published by
adsb.lol , used under the
Open Database License (ODbL). Heat-map brightness is the number of distinct aircraft
through each cell, not the number of position reports.
What is missing.
Aircraft without ADS-B - many classics, and anything without an electrical system -
are invisible to this method, so the real totals are higher. Consider these a floor,
not a census.
