Rocket anti-aircraft fire

[445BombGroup]

Greetings:

In going through some of the post mission reports, I've run across references to ground-to-air rockets being fired against bomber formations. On one mission near Orly, France, a B-24 was hit by a rocket and completely destroyed. The crew reporting the incident said they saw a smoky trail leading from the ground up to the bomber just before it exploded.

I was wondering what types of rockets these would be; did they have any sort of guidance system, or where they free flight? I know of an add-on field modification to the Fw-190 to carry 2 8,0cm rockets for air-to-air use.

Thanks in advance for any help you can lend.
