Iran airspace NOTAM claim circulates

X posts on May 22 said Iran had “cleared” its airspace and grounded or rerouted flights across the country. The documents and aviation mirrors available online on May 23 pointed to a more limited restriction: a NOTAM covering airports in the western part of the Tehran flight information region, not a blanket closure of all Iranian airspace. The claim spread across crypto-focused accounts, including a widely shared post by Crypto Rover on X. Iran’s own aeronautical information portal says valid NOTAMs are published there, but the underlying state sites were not fully accessible in public web checks reviewed for this report. ### What did the viral posts actually claim? Crypto Rover and other X users on May 22 framed the development as Iran’s airspace being emptied or shut down. The posts cited a NOTAM but did not, in the versions reviewed through search results, identify the issuing authority or quote the full text of the notice. The social-media framing moved faster than any official explanation visible in public web results. (ais.airport.ir) ### What does the available NOTAM say? NOTAM A1010/26, as mirrored by Notamify and indexed by NOTAM tracking pages, said “all airports in west part of Tehran FIR are clsd” except eight listed airports operating from sunrise to sunset. The same mirrored text said all previous permissions were suspended and that new permission had to be requested from the civil aviation authority for civil IFR passenger flights at those airports. The notice was shown as effective from 20:46 UTC on May 22 until 08:30 UTC on May 25. (notams.online) Iran International, citing Iranian air traffic authorities, separately reported that civil passenger flight clearances in the western part of the Tehran FIR had been suspended except for eight airports, also describing a daylight-only operating window. That account matched the text shown on NOTAM mirrors reviewed for this report. ### Does that mean all of Iran’s airspace was closed? Notamify’s Middle East dashboard on May 23 described the “Tehran FIR west sector” as closed to overflights and said the east sector was open with specific air traffic control and equipment requirements. (notamify.com) That description does not match the broader social-media claim that all of Iran’s airspace had been cleared. Reuters was cited by News18 last month as reporting that Iran’s airspace was partially open as of April 19, 2026, under a phased reopening plan by the Iranian Civil Aviation Organization. (iranintl.com) That earlier status is consistent with a country operating under layered restrictions rather than a simple open-or-shut condition. (notamify.com) ### Where would an official Iranian notice normally appear? The Iran Aeronautical Information Management portal says it operates under the authority of the Iranian civil aviation authority and provides “a list of valid NOTAM according to the applicable ICAO regulations.” ICAO’s own NOTAM page says its global repository collects actual NOTAMs on a 12-hour schedule and allows keyword searches. Those are the formal channels or repositories where pilots and dispatchers would expect notices to surface, rather than through screenshots on X. (news18.com) ### Why did the claim travel so widely? The May 22 posts appeared in crypto channels already primed for geopolitical headlines. The jump from a western Tehran FIR restriction to claims that Iran’s entire airspace had been emptied appears to have come from social-media paraphrasing, not from the narrower text shown in the mirrored notice reviewed online. That is an inference based on the gap between the viral wording and the available NOTAM text. (ais.airport.ir) May 25 is the next concrete date in the notice trail. NOTAM A1010/26 was shown by aviation mirrors as remaining in effect until 08:30 UTC on that date, and the Iran AIM portal is the place its valid NOTAM list would normally appear under Iranian civil aviation authority procedures.
