All the bidders were bidding under the same terms and conditions.
Golfin withdrew and - just perhaps - the reasons stated in the Journal are not the complete picture.
Several of the bidders may not have had the finance to support their bids. This sort of thing happens all the time.
Don't expect any news until the contracts are signed & the deal is done - normal business practice.
And to end on a hopeful note -
There may well be flying training again at Newcastle.
