Danny, there are some inconsistencies in this. There is a great website you can use to get an overall picture of events that day: here is a link to the starting page:

Click on the Missions circle and enter the date 11/29/1943. That gets you to the official mission report page, but you need to dig through the other links, in particular Mission Reports and Mission Statistics. It takes a little time to follow all the resulting links. (If you have access to fold3.com you can also follow up on the actual MACRs.)
It looks like some of the planes took off around 10 to 10:30 in the morning. The weather was terrible and I notice is that at least 200 planes did not complete the mission. Bremen is actually bombed according to some the info there around 14:40, which is about the time given for the Swope crash. That leads to the question of did they actually go to Bremen or had they aborted earlier or is the time (or the location) when they made the radio call in the Swope MACR incorrect?
