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.

Rainbow
An individual raindrop has a different shape and consistency than a glass prism, but it affects light in a similar way. When white sunlight hits a collection of raindrops at a fairly low angle, you can see the component colors red, orange, yellow, green, blue, indigo and violet -- a rainbow. For simplicity's sake, we'll only look at red and violet, the colors of light on the ends of the visible light spectrum.
The diagram below shows what happens when the sunlight hits one individual raindrop.
When the white light passes from air into the drop of water, the component colors of light slow down to different speeds depending on their frequency. The violet light bends at a relatively sharp angle when it enters the raindrop. At the right-hand side of the drop, some of the light passes back out into the air, and the rest is reflected backward. Some of the reflected light passes out of the left side of the drop, bending as it moves into the air again.
In this way, each individual raindrop disperses white sunlight into its component colors. So why do we see wide bands of color, as if different rainy areas were dispersing a different single color? Because we only see one color from each raindrop. You can see how this works in the diagram below.
When raindrop A disperses light, only the red light exits at the correct angle to travel to the observer's eyes. The other colored beams exit at a lower angle, so the observer doesn't see them. The sunlight will hit all the surrounding raindrops in the same way, so they will all bounce red light onto the observer.
Raindrop B is much lower in the sky, so it doesn't bounce red light to the observer. At its height, the violet light exits at the correct angle to travel to the observer's eye. All the drops surrounding raindrop B bounce light in the same way. The raindrops in between A and B all bounce different colors of light to the observer, so the observer sees the full color spectrum. If you were up above the rain, you would see the rainbow as a full circle, because the light would bounce back from all around you. On the ground, we see the arc of the rainbow that is visible above the horizon.
Sometimes you see a double rainbow -- a sharp rainbow with a fainter rainbow on top of it. The fainter rainbow is produced in the same way as the sharper rainbow, but instead of the light reflecting once inside the raindrop, it's reflected twice. As a result of this double reflection, the light exits the raindrop at a different angle, so we see it higher up. If you look carefully, you'll see that the colors in the second rainbow are in the reverse order of the primary rainbow.

De Havilland Canada's first post-war aviation project was to design the Chipmunk as a tandem, two-seat, single-engined primary trainer aircraft, being typically employed as a replacement for the de Havilland Tiger Moth biplane.
Among the tens of thousands of pilots who trained in or flew the Chipmunk for pleasure was veteran aerobatic and movie pilot Art Scholl. He flew his Pennzoil Special (above) at air shows throughout the 1970s and early '80s, thrilling audiences with his skill and showmanship and proving that the design was a top-notch aerobatic aircraft.
Art Scholl purchased the aircraft in 1968. He modified it to a single-seat airplane with a shorter wingspan and larger vertical fin and rudder, and made other changes to improve its performance. Scholl was a three-time member of the US Aerobatic Team, an air racer, and a movie and television stunt pilot. At air shows, he often flew with his dog Aileron on his shoulder or taxied with him standing on the wing.
Today the aircraft is displayed in the National Air and Space Museum's Udvar-Hazy Center at Chantilly in Virginia, USA.

A de Havilland Canada DHC-6-300 Twin Otter sitting at the North Bay airport. This airframe (C-FOPI) was built in 1969.
Alongside the pair of Boeing 737s operated by Malawi Airlines, the third aircraft in their fleet is this Dash-8, seen parked at Lilongwe Airport.
I've seen this aircraft in Harare in 2014 and 2015, and it was previously branded Malawian, but the airline name was subsequently amended to just Malawi (Airlines)
