aviation minister said Kingfisher needed at least 10 billion rupees ($185.65 million) to restart its grounded operations and must also demonstrate an ability to sustain itself for at least 6 months.
A senior government source said India was willing to support a rescue plan from Kingfisher if it could settle months of salary owed to frustrated employees.
ILFC, or International Lease Finance Corp, has itself rebounded since its seeing funds squeezed by the credit crisis, and is in the midst of being sold to a Chinese consortium.
The lessor said it had broadened funding sources and reduced their cost in 2012, and had $2.9 billion in unrestricted cash.

Just as airlines overbook seats to protect their income in the event passengers cancel, plane manufacturers use exactly the same strategy on the airlines by selling more aircraft than they can actually make in the expectation that some will cancel.
"I don't know if they are over-selling;
