It’s a random figure on a social media group with no factual backup .
however I fully expect the figure to be substantial as Peel have planning permission sorted around the edge of the airport, and if the worst happens at some point they will get planning.
whoever buys it has to accept that. The upside is if it fails they also have the development option.
it is one of the issues for uses that require big spaces of open land.
I am sure that all involved know all of this.
