Problem: The disadvantage of the ski-jump is the penalty it exacts on aircraft size, payload, and fuel load (and thus range); heavily laden aircraft can not launch using a ski-jump because their high loaded weight requires either a longer takeoff roll than is possible on a carrier deck, or assistance from a catapult or JATO rocket. For example, the Russian Su-33 is only able to launch from the carrier Admiral Kuznetsov with a minimal armament and fuel load. Another disadvantage is on mixed flight deck operations where helicopters are also present such as a US Landing Helicopter Dock or Landing Helicopter Assault amphibious assault ship a ski jump is not included as this would eliminate one or more helicopter landing areas, this flat deck limits the loading of Harriers but is somewhat mitigated by the longer rolling start provided by a long flight deck compared to many STOVL carriers.
What do heavily laden aircraft sometimes require the assistance from?

Answer: a catapult or JATO rocket

Problem: The insect outer skeleton, the cuticle, is made up of two layers: the epicuticle, which is a thin and waxy water resistant outer layer and contains no chitin, and a lower layer called the procuticle. The procuticle is chitinous and much thicker than the epicuticle and has two layers: an outer layer known as the exocuticle and an inner layer known as the endocuticle. The tough and flexible endocuticle is built from numerous layers of fibrous chitin and proteins, criss-crossing each other in a sandwich pattern, while the exocuticle is rigid and hardened.:2224 The exocuticle is greatly reduced in many soft-bodied insects (e.g., caterpillars), especially during their larval stages.
The cuticle has how many layers?

Answer: two

Problem: The New Haven Green is the site of many free music concerts, especially during the summer months. These have included the New Haven Symphony Orchestra, the July Free Concerts on the Green in July, and the New Haven Jazz Festival in August. The Jazz Festival, which began in 1982, is one of the longest-running free outdoor festivals in the U.S., until it was canceled for 2007. Headliners such as The Breakfast, Dave Brubeck, Ray Charles and Celia Cruz have historically drawn 30,000 to 50,000 fans, filling up the New Haven Green to capacity. The New Haven Jazz Festival was revived in 2008 and has been sponsored since by Jazz Haven.
