I am not sure what information you have (or are looking for) but DL Bourner was FE on No. 426 Squadron Halifax (LW200) which collided in mid- air with a No. 428 Sqdn Lancaster (KB768) on which CN Collingwood was FE.
Both aircraft crashed near Rugby, Warwickshire.
If you can let us know what details you are looking for then I am sure others will be able to expand on this for you.
Regards
Pete
