Game Crashes

[jskrause]

The game crashes for me when I click to start flights on a new route.  Here are the steps that lead to the crash.

1. I had three aircraft of the same type. Boeing 720 (707-020)
   
2. I purchased a new aircraft of a different type. Vickers Viscount 810
   
3. I created a new route using the new aircraft.  
   
4. The route used the new aircraft and flew from one of my current airports to a new airport.
   
5. The game crashes when I attempt to start flights on the new route.
   

I have tried deleting the route and recreating it.  I have also tried changing the cities.  It always crashes when I attempt to start flights.

Thanks! 


Here is the last part of the log.
