Maybe they can simulate the failure rates experienced by the United States aircraft Industry?
If we look at the US Aviation industry, 1 in every 182 airframes built from January to October 1943 was a total write off and destroyed in crashes during Ferrying.
We can use today's aviation accident statistics to get a ballpark idea of the number of emergency landings. According to the FAA accident data base, you have ~98% of a making a daylight emergency landing without injury or major damage.
That puts the ballpark figure for emergency landings in the US Aviation industry at 14100 incidents or about 17% of the aircraft produced had an issue which forced termination of the flight in the first few hours of operation.

As a base, the average accident rate is about 14% on the initial flight for a new aircraft and 5% on the second flight.
Given the frantic pace of wartime production I would expect that rate to be somewhat higher.
Of course that is just raw data before the newly manufactured aircraft is delivered. Airplanes are complicated machines and it is perfectly normal to have issues in the first few hours of operation.
All Air Forces flew acceptance flights to test new aircraft before accepting them.

Undercarriage tests followed before the aircraft was lowered onto its wheels and rolled out of the final assembly hall. It was then led to the firing stand to test its weapons and also for centering the compass on the rotable compass adjustment stand. After fueling, and a last check of all functions, the engine was subjected to a test run, where after the Bf-109 stood ready for a works flight. In the initial test flight it was climbed to 8,000m (26,250ft), the aircraft and the engine was thoroughly checked out and performance data compared with that required. In the event that faults were found, these would be recorded and eliminated after the landing. This was then followed by a works test flight in which it could be established how many of the faults had been rectified. Where no further faults were determined on this flight, the aircraft was then release for acceptance by the BAL. In Regensbug, several pilots (Obermeier, Lohmann and others) were authorized by the RLM to carry out Bf 109 acceptance flights for the BAL. After their acceptance by the BAL, the aircraft were then taken over by the Luftwaffe.

Just some facts for you guys to digest! Have fun!
