On some missions the Mission Commander decided to try to go below the cloud cover to find the target. I wanted to include this as a rule in B-26 but here's another rule that will make it more complex, so it will either be a house rule, add-on or optional.
If the weather in the target zone prevents you from finding the aim point, you may try to go around and descend to a lower column. On your next bomb run, roll on TZ-1, Weather using the weather result from your first run. If the result is equal to or worse condition, it is equal to your first result. You may try again, but in the core game you cannot go lower than Column A on MP-2, Altitude.
