Thousands of people are backing an online bid to save one of two remaining cross channel hovercraft.
The Princess Anne is under threat as the site in Lee on Solent, they're kept on is being sold.
She's one of the main points of the Hovercraft Museum - housed next door to the SRN4.
"The SRN4's are the centre point of the museum and our most important exhibits. Many people come simply to see these huge relics from a bygone age and their loss would be an enormous blow to the museum.
"But more important than that is the fact that they are piece of British history, the like of which we will never see again. The Hovercraft Museum trust is dedicated to preserving them and we hope that a deal can be reached to allow this to happen.
"The final decision is out of our hands and this has all happened at very short notice but we will do everything in our powers to protect at least one of these national treasures."
