Yes, that is the case. I didn't realize it was 6 months, but knew it was something like that.

I just hate missing certain aircraft because I couldn't be in the game in time to buy them. The "here today, gone tomorrow" scenario is a little lame.

Aircraft on which production has ended should still be available in the used plane inventory.

It is not realistic that just because a certain airliner is no longer being manufactured, it completely disappears from global availability.

Production end plus 20 years to fade out is more like the world of used aircraft.
