Very common misconception. If you posted it through the Google
interface, then yes you can delete it off the Google system.

But as soon as it was posted on Google, it got relayed to the Usenet
network, where it will stay forever.

For example, some recent postings from "Dee" were deleted off Google,
and remain on Usenet, where people are free to see and reply to them.

R.A.S. is NOT a Google Group, no matter how many people believe that it
is.

You can always go to https://groups.google.com/g/rec.aviation.soaring , click on the top right corner drop down menu, then click on the "Delete" option, if it was really just an inadvertent post, so that it will not be unsuccessfully searched for glider- or soaring related content.

This post was also an accident, right? Same, delete it:
