I have enough reliable detail from the Bing news search to write an accurate, neutral summary without over-specifying facts I can't confirm (like exact dates).

SUMMARY:
A public consultation has opened on airspace plans for the reopening of Doncaster Sheffield Airport, marking what officials have called a "crucial" step in the process of bringing the site back into operation after roughly four years of closure. The move follows approval from the Civil Aviation Authority to proceed to this stage, and residents and other stakeholders are now being invited to submit their views before any changes are finalised.

The reopening project is being backed by significant public funding, including a £57 million loan as part of a wider package worth around £160 million. The plans have proved divisive: some in the local area welcome the scheme as a boost for regeneration and jobs, while others have raised concerns over the use of public money, and Reform UK's Doncaster branch has voiced opposition. Supporters have also called on regional figures, including Manchester Mayor Andy Burnham, to back the project, which has previously faced setbacks such as infrastructure damage caused by a vermin infestation.
