Timeline
Three clocks, one reading line
Shared calendar-day axis, from left to right. Bars mark days or reporting windows, not durations. Publication and revision clocks are not event clocks. Missing clocks remain unknown; the table gives all available precision and source links. The plot follows recorded calendar dates; time zones may differ. It establishes neither within-day order nor causality.

What remains uncertain?
- Was a drone established? A published investigation or identification could resolve this.
- Who operated it, and why? An attributed investigation finding is missing.

How to read this table
Reading aid only. Switch off a source or its recorded family to inspect the remaining visible support for exact claim texts. Evidence status is not recalculated. Shared wording or a shared family does not prove independence. Only recorded links labelled “supports” count here; context and contradiction links are not support. The dossier itself is unchanged.
| Claim | Supporting sources | Visible support |
|---|---|---|
| Police describe initial reports shortly before 22:00 on 24 September. | [1] | Support remains visible |
| Police state the airports were not closed in connection with the reports. | No supporting link recorded | No supporting link recorded |
| The airport co-owner account reports no cancellations or diversions. | No supporting link recorded | No supporting link recorded |
What we know
Police said the airport had not closed; the municipal account reports no cancellations or diversions because the observations occurred outside scheduled flight operations. No physical damage or casualties established here.
Police are the original sighting account. The municipality, a co-owner of the airport, supplied a separate statement about the local operational outcome, relayed by SønderborgNYT. This does not independently identify a drone; possible attack language is an official concern, not an established hostile act.
Data
- No structured detail recorded
- Hit / damaged · Fell near · Intercepted (claimed) · Human consequences · Effects
What remains unknown
The exact type, number, operator and motive are not established. The date represents the start of the reported overnight window, not the 25 September publication date. No final case-specific outcome established; no attribution from the wider Danish wave. This is a separate physical airport from Aalborg, Billund and Esbjerg.
No operator or responsible organisation established by these sources; no criminal charge or conviction is asserted.
