Bombers not flying strategic bombing missions

[Etude]

I had War In The West about 10 years and played it for a few months. I got quite accustomed to the interface, but it's been so long since I that played I've forgotten most of it.

Anyway I have had some trouble lately with bombing missions. I have been using RAF Bomber Command and 8th Air Force to do the usual bombing of western Germany and Holland. I create about 3 strategic bombing missions per turn for Bomber Command and the 8th Air Force. Usually I can get two successful missions per HQ.

However recently I have changed my bombing strategy to hit the V weapons in northern France. I order Bomber Command and 8th to do bombing missions on the V weapon sites in northern France. But I haven't any bombing missions flown. Even after 6 turns, nothing And it's not to do with the weather, I'm in August and the weather is clear. It says I have hundreds of bombers selected for the missions, but not a single one ends up flying.

So I'm confused as to why I can't bomb France. It's much closer, just across the Channel! Any ideas what is wrong?

EDIT - the problem seems to be about the V Weapon sites. I can hit other targets in norther France. But not V weapons. They have two asterisks beside their name in the target list . But I don't know that those asterisks mean
