I was looking at those pictures of the cross-hatch contrails above the b-17 formations.
After the Scenario, I know why. It's work for a P-51 to match the bomber speed and still stay in the air at 30k. The cross-hatch allows you to keep up your air-speed and still stay with the bombers.
Those of us that love WWII planes really appreciate the immersion factor of the Scenarios.
Thanks to all who make it possible.
