From my DD, the Air Cuba that NSEH is focused on has zero planes and does not appear to have any notable assets. http://www.air-cuba.com
Now there is another Air Cuba based in Romania that has numerous aircraft and a worldwide presence. Unfortunately, this company has nothing to do with the one NSEH is talking about. http://aircuba-en.webnode.fr/our-offices/
There revenue for the last year was $130,000. They had 3 or 4 employees. Not enough revenue to pat wages. And $130,000 isn't enough to do maintenance on the planes for even 2 months. That isn't even enough to buy one engine.
