From "My Diary of Ops" - the notebook of Flight Sergeant E. Burnett, 419 Squadron R.C.A.F.
(part of a series)
Mon June 1/42
Took off from base with own crew in own air craft at approx 2230 hrs.
Target Essen. Which we never reached? Due to engine trouble and the T/R 9 not in working order. We were only 15 mi off Dutch coast when we turned back dropping our load of incendiaries into sea. Landed at Base approx 2420 hrs. Learned on return from other A/C that visibility was very poor 10/10 clouds. So it was just as well we did turn back. All returned safely.
