Ground crew swarm all over a Halifax at the "Caribou" 1664 Heavy Conversion Unit in the RCAF Bomber Group which is commanded by G/C E.L. Wurtele of Montreal. The big aircraft are brought into hangars only for major repairs and overhauls; all routine work must be done at their dispersal points, regardless of weather or time of day. DND photo.
