I found this in a copy of the "Union Jack - British Forces Daily" paper for 8th May 1945. I didn't realise this technique was used in WW2.
The 109 above is a Fw 190 Yes Mistels as they were called were used quite a bit. The one in the photo may be a trainer. Many had the cockpit on the lower plane removed and replaced with a huge shaped charge warhead. This made them very suitable for hardened targets. The usual format was to use an Me 109 as the top plane when the bomber component was an inline engined aircraft and a FW 190 for the others
AFAIK no but I believe there was a plan to use them to attack the fleet at Scapa Flow that was never implemented. They were very vulnerable to fighter attack and showed up well on radar
The attack on Scapa Flow was to be carried out by 12 Mistel of 6/Kg200. Thew lower components were all fitted with shaped charge warheads. The attack was to be launched from Denmark. Guide buoys had already been laid by U boat. The pilots were on a promise of a Knight's Cross if they got back. The idea was to approach at low level under cloud cover. The mission was aborted because Mistels staging to the launch airfield were intercepted by P51s of 55FG returning from escorting a raid on Berlin
There was also a version with an Arado 234 as the lower component I think the top photo was the test vehicle for this concept.
