History
Bombardier's de Havilland Dash 8 has proven to be a popular player in the regional turboprop airliner market. De Havilland Canada began development of the Dash 8 in the late 1970s in response to what it saw as a considerable market demand for a new generation 30 to 40 seat commuter airliner. The first flight of the first of two preproduction aircraft was on June 20 1983, while Canadian certification was awarded on September 28 1984. The first customer delivery was to norOntair of Canada on October 23 1984. Like the Dash 7, the Dash 8 features a high mounted wing and Ttail, and has an advanced flight control system and large full length trailing edge flaps. Power meanwhile is supplied by two Pratt & Whitney Canada PW120 series (originally designated PT7A) turboprops. Initial Dash 8 production was of the Series 100, which was followed by the Series 100A in 1990. The 100A introduced a revised interior with extra headroom and PW120A turboprops. The Series 100B was offered from 1992 with more powerful PW121s for better climb and airfield performance. Production since switched to the improved performance Dash 8-200. Announced in 1992 and delivered from April 1995 the -200 features more powerful PW123C engines which give a 56km/h (30kt) increase in cruising speed, as well as greater commonality with the stretched Dash 8300. The 200B derivative has PW123Bs for better hot and high performance. From the second quarter of 1996 all Dash 8s delivered have been fitted with a computer controlled noise and vibration suppression system (or NVS). To reflect this the designation was changed to Dash 8Q (Q for `quiet'). In 1998 that was changed again to Dash 8 Q200 when a new interior was introduced.

Chesapeake Bay

-was formed nearly 12,000 years ago when glaciers melted and flooded the Susquehanna River valley;

-is—most historians believe—named after the Algonquin word chesepiooc, meaning "great shellfish bay;"

-is approximately 200 miles long, stretching from Havre de Grace, Maryland, to Norfolk, Virginia;

-has an average depth of 21 feet (the deepest part of the Bay, a.k.a. "The Hole," is 174 feet deep and located off of Bloody Point, southeast of
Annapolis, Maryland;

-ranges from 3.4 to 35 miles wide;

-holds more than 15 trillion gallons of water;

-supports 348 species of finfish and 173 species of shellfish;

-supports more than 3,600 species of plant and animal life, including 2,700 types of plants and more than 16 species of underwater grasses;

-is fed by 50 major tributaries (or streams and rivers) every day—the largest of these are the Susquehanna, Potomac, Rappahannock, York, and James;

-produces more than 500 millions pounds of seafood harvest each year.

Crepuscular rays

Crepuscular rays /kr?'p?skj?l?r/ (more commonly known as sunbeams, sun rays, or god rays), in atmospheric optics, are rays of sunlight that appear to radiate from the point in the sky where the sun is located. These rays, which stream through gaps in clouds (particularly stratocumulus) or between other objects, are columns of sunlit air separated by darker cloud-shadowed regions. Despite seeming to converge at a point, the rays are in fact near-parallel shafts of sunlight. Their apparent convergence is a perspective effect, similar, for example, to the way that parallel railway lines seem to converge at a point in the distance. The sun rays do converge to the sun, but the sun is much further away than the rays might make it look like.[2]

The name comes from their frequent occurrences during twilight hours (those around dawn and dusk), when the contrasts between light and dark are the most obvious. Crepuscular comes from the Latin word "crepusculum", meaning twilight.[3]
