I am unable to trace such a data upload but would suggest that you may have attempted to use the wrong tool for such as you describe.
The "Update/Correct aircraft data" is for the uploading of data related to the listed parts/performance of aircraft.
For such as you describe, I suggest you upload the brief history using the "Comment on this aircraft" facility which is also located in the top LH corner of the profile page.
