Roger! Roger!

We have at current count 4 house martin nests on our property.

Since i was a little boy, i've looked at house martins and imagined them in their own Battle of Britain. Roger! Roger! bandits at two......huhuhuhuhuhuhuh as they shoot down the enemy.

For weeks now, I've been trying to catch these suckers in flight, well I've given up, this is the best I could manage.

Unless anyone has any tips for me.
