QUES: In 1974, the unmanned AstroFlight Sunrise plane made the first solar flight. On 29 April 1979, the Solar Riser made the first flight in a solar-powered, fully controlled, man carrying flying machine, reaching an altitude of 40 feet (12 m). In 1980, the Gossamer Penguin made the first piloted flights powered solely by photovoltaics. This was quickly followed by the Solar Challenger which crossed the English Channel in July 1981. In 1990 Eric Scott Raymond in 21 hops flew from California to North Carolina using solar power. Developments then turned back to unmanned aerial vehicles (UAV) with the Pathfinder (1997) and subsequent designs, culminating in the Helios which set the altitude record for a non-rocket-propelled aircraft at 29,524 metres (96,864 ft) in 2001. The Zephyr, developed by BAE Systems, is the latest in a line of record-breaking solar aircraft, making a 54-hour flight in 2007, and month-long flights were envisioned by 2010. As of 2015, Solar Impulse, an electric aircraft, is currently circumnavigating the globe. It is a single-seat plane powered by solar cells and capable of taking off under its own power. The designed allows the aircraft to remain airborne for 36 hours.

What is the name of the aircraft circling the globe in 2015 via solar power?
What is the answer?
ANS: Solar Impulse
QUES: In 1954, then-mayor Richard C. Lee began some of the earliest major urban renewal projects in the United States. Certain sections of downtown New Haven were redeveloped to include museums, new office towers, a hotel, and large shopping complexes. Other parts of the city were affected by the construction of Interstate 95 along the Long Wharf section, Interstate 91, and the Oak Street Connector. The Oak Street Connector (Route 34), running between Interstate 95, downtown, and The Hill neighborhood, was originally intended as a highway to the city's western suburbs but was only completed as a highway to the downtown area, with the area to the west becoming a boulevard (See "Redevelopment" below).

What New Haven mayor is responsible for projects that placed the city among the forefront of urban renewal in the U.S. circa 1954? 
What is the answer?
ANS: Richard C. Lee
QUES: The greater advances of the Soviet space program at the time allowed their space program to achieve other significant firsts, including the first EVA "spacewalk" and the first mission performed by a crew in shirt-sleeves. Gemini took a year longer than planned to accomplish its first flight, allowing the Soviets to achieve another first, launching Voskhod 1 on October 12, 1964, the first spacecraft with a three-cosmonaut crew. The USSR touted another technological achievement during this mission: it was the first space flight during which cosmonauts performed in a shirt-sleeve-environment. However, flying without spacesuits was not due to safety improvements in the Soviet spacecraft's environmental systems; rather this innovation was accomplished because the craft's limited cabin space did not allow for spacesuits. Flying without spacesuits exposed the cosmonauts to significant risk in the event of potentially fatal cabin depressurization. This feat would not be repeated until the US Apollo Command Module flew in 1968; this later mission was designed from the outset to safely transport three astronauts in a shirt-sleeve environment while in space.

The US Apollo Command Module flew without spacesuits in what year?

1968
