Paul,
Thanks for making the detour to show us these pictures.
De Jager crashed on 18 May 1944 in a mid-air collision with F.C.M. Brogtrop (Hellcat tail numbers (JV182 and FN376).
"2E LT VL. M.L. K.N.I.L." stands for "2nd Lieutenant Airman Military Aviation Royal Netherlands East Indies Army".
Den Hollander flew Hellcat FN390 when he crashed on 28 april 1944.
"OFF. VL. 3E KL. KM" stands for "Flying Officer 3rd Class Royal Navy".
Like so many others, they got killed while training. May they rest in peace
Hanno
