I notice that you have added "hangar" to the photo I sent of the 421 Squadron Sabre's on "the line" in Deci. (This error has been corrected). This is incorrect Ren in that we did not have a hangar in Deci or Rabat for that matter in the days I was there. If we had to do any major work in Rabat we borrowed space in the FAF hangar. In Deci we had a large tent where the aircraft could be put under cover while doing major maintenance. Whether a hangar was ever built for the RCAF in Deci I could not say.
The reason us Aircraft Techs refer to "the line" comes from the fact that the Engineering Officers used to (actually they still do) have a long red, black or white line painted on the tarmac where the aircraft were to be parked. We had to place the nose wheel on that line at a proper angle whether towing it in with a "mule" or guiding in the pilot after a sortie. Some EO's went so far as to paint positioning squares where all 3 aircraft wheels were to be when it was parked. This is why all the Sabres look so perfectly "in line" when parked. We never had this done on "the ramp" which was the area in front of the hangar but always tried to park them uniformly nontheless. The dispersal areas consisted of "buttons" where 2 Sabres could be parked on alert. Many of the old WW2 NCOs also referred to the area in front of the hangars as the "tarmac". The origins of this name come from the originator of asphalt who was a Scot named MacAdam. Originally his invention was called "tar MacAdam" which eventually became shortened to "Tarmac" as we know it today.
