[Plt Off JRB Meaker]

From early days I wrote down on a post it note the wingspan measurements of the enemy aircraft in COD and stuck it on my monitor.

It surprising how quickly you remember these measurements when looking at them everyday.But it was also reasuring having them there to act as an aid memoir.

As regards convergence,whilst being interview a few years ago Pete Brothers from 32 Sqn said that he would have his convergence set at 50 yards which is an amazingly short distance.

He said that he would make surprise attacks,get right up close and then blast away,having to do this to make up for the poor knock down power of the .303 rifle round that made up the Brit ammo in his Hurri.

The Brit RAF command did not like this idea,in 1939 the std convergence was 400 yards,which obviously carried over into 1940.I think they allowed the aces to do as they pleased and would turn a blind eye to this practice.
