Does this picture, with dust rising and a jet's wing in the foreground, capture the August 26, 2021, explosion at the Kabul airport? No, that's not true: The picture in the screenshot below was taken on August 16, 2021, by a photographer for Agence France-Presse.
The claim appeared in a Facebook post (archived here) published on August 26, 2021. It was captioned:
Blast near Kabul airport Eastern Gate. Potentially suicide bomber.
This is what the post looked like on Facebook at the time of writing:

A suicide bombing did happen at the Kabul airport in Afghanistan on August 26, 2021, killing 13 U.S. servicemen and at least 99 Afghan civilians. (The Pentagon said there was one bombing, not two, on August 27, 2021.)
The image in shown in the Facebook post was taken 10 days earlier and shows soldiers standing by as a helicopter takes off from Kabul airport, kicking up a dust cloud. Getty Images' photo archive shows the photo was taken on August 16, 2021, by Wakil Kohsar for Agence France-Presse.
