Actually, the success story of the past 30 years has been European collaboration, especially with Airbus. 50% by value of the A380 is British-built, principally the wings and the engines.
Presumably, Airbus will be looking elsewhere for these items post-Brexit. This will be a massive loss to the UK economy.
The other major industry that will go is UK car-building, a major export earner.
These 2 losses combined will wipe £billions off the UK economy, thank you very much.
