The commemorative anniversary logo or emblem was suggested to celebrate this landmark anniversary. After researching the information there is much relevancy to the anniversary logo as well as stating the obvious.
The 7 clearly celebrates the decades we are celebrating since the flight of the first Jet propelled aircraft. It also doubles up as a symbolic open canopy of extended landing gear with the 0 being a cross section of an aircraft wheel.
The design of the 0 signifies the turbine intake and circular movement of the jet engine.
Sitting proudly in the centre are the initials DH.
The silhouette of the de Havilland Comet aircraft flying from the anniversary logo at the shown angle signifies the success expected from such an innovation and the speed and accelerated climb of a jet engine aircraft to the height at which it was to be flown.
However, due deference is paid to the cost of this ground breaking innovation and the souls that were lost before metal fatigue was identified as a problem after the plane went into service. Despite stringent testing under every conceivable condition nobody had flown a jet propelled aircraft at altitude before. Very little was recorded or available on the on metal fatigue in pressurised cabins, it just did not exist. Although hours and hours of stringent testing took place before entering the de Havilland Comet into commercial service there was no data available for anyone to foresee the problem that ensued. The innovative design of square windows and use of Aluminium that was punch riveted caused the metal to split from the weak point on the angled corners and peel away from the fuselage.
When this was established, the design was immediately changed and from that time all aircraft have circular, oval or rounded shaped windows that have a much stronger tolerance over a larger area and the punch riveting method revised.
For this reason, and in remembrance, the logo is predominantly and purposely black with just a small section in silver which is the colour of the original prototype and offers a poignant reminder to the section of fuselage that peeled off during flight causing the tragic loss of lives of these pioneering passengers.
It is a poignant reminder to us all that travelling internationally by air while still statistically the safest form of transport, it is not without risk as so recently illustrated by the recent grounding of the Boing 737 Max at the time of writing.
