Well so far this has been a most illuminating post - Not! No idea if an aircraft really has been repossessed, no idea from whom if it has, no idea whether I should worry about being paid by a particular company or not.
Hamish 123 is right, of course: malicious rumours or false rumours can do damage and there might be the possibility of redress. But if it is true - and someone muct know if it is - then I'd rather know.
Just think about why an aircraft might be repossessed.
