Plans have been put forward to Plymouth City Council by a group that wants to see the city connected to the world within a decade.
The Viable company wants to buy the freehold of the former airport site and intends to have flights to Britain and western Europe within two years.
But site leaseholder Sutton Harbour Holdings, which closed the airport last year, has also revealed its own "masterplan" to build on the site.
The contents of Plymouth City Airport go on show today (Thurs) before being auctioned off next week. That's despite calls for the sale to be postponed so a rescue plan can be developed.
Hundreds of items are up for grabs from the fire engines to the X-ray machines in departures.
