I'm pretty sure the Mossie went all the way to Berlin in daylight, don't know if it took a full 4000lbs with it though.
No pretty sure about it at all. 6 Mossies in two waves did it on 30th January 1943. The first attack by 3 aircraft from 105 Sqn was timed to attack the main radio station at the exact time that Göring was starting a well publicised morning radio broadcast celebrating the Nazi's 10 years in power. 3 Mossies from 139 Sqn repeated the attack in the afternoon to disrupt a planned speech by Goebbels. Both attacks were successful in that they caused extreme embarrassment to the Nazi leadership (though one mossie and its crew were lost on the second attack). Plenty of 4000lbs cookies dropped on Berlin by mossies though almost all at night.
