These are published materials composed of the full scientific and technical assessment of climate change, generally in three volumes, one for each of the Working Groups of the IPCC, plus a Synthesis Report. Each of the Working Group volumes is composed of individual chapters, an optional Technical Summary and a Summary for Policymakers. The Synthesis Report synthesizes and integrates materials contained within the Assessment Reports and Special Reports and is written in a non-technical style suitable for policymakers and address a broad-range of policy-relevant but policy-neutral questions. It is composed of a longer report and a Summary for Policymakers.
The Comet was an all-metal low-wing cantilever monoplane powered by four jet engines; it had a four-place cockpit occupied by two pilots, a flight engineer, and a navigator.  The clean, low-drag design of the aircraft featured many design elements that were fairly uncommon at the time, including a swept-wing leading edge, integral wing fuel tanks, and four-wheel bogie main undercarriage units designed by de Havilland.  Two pairs of turbojet engines (on the Comet 1s, Halford Ghosts, subsequently known as de Havilland Ghost 50 Mk1s) were buried into the wings. 
Before one is admitted to a Master's program, one must have obtained a bachelor's degree in the same field of study at the same level. This means that someone with a HBO Bachelor's degree can normally not start directly with a WO Master, their scientific deficiencies are bridged in a half-year or full year program after which they can continue into the WO Master program. There might also be additional requirements such as a certain higher than average GPA, sometimes it's possible to complete the bridging program parallel to the HBO Bachelor. Note that completing this program does not grant the student a WO Bachelor's degree but merely entrance to the Master and that some two year WO Masters allow HBO Bachelor's degree holders in directly.
