Where are your details showing that one of the deals on the table currently are not part of, or a continuation of, those earlier orders??? Talking out of your donkey.
Do you know how many years Douglas had firm orders for the DC-3, or Lockheed had for the Connie, or Boeing had for the 747 before they were produced? Time, brother, a matter of time. They will produce or go bankrupt... Time will tell...
