The maintenance history on those aircraft is already fucked... it's coming up on a year of no spare parts or authorised maintenance procedures, together with the aircraft sitting idle outdoors in a country with absolutely shit weather conditions. I'm 100% certain that they've been properly covered, serviced and periodically spun up, and that no-one stole the fuel and forged maintenance records at all...

Due to the above, even if the aircraft came back into the ownership of the original companies, you could never really trust them again. If you leased them out and any accident were to occur, the leasing company would be absolutely fucked.
