PAL, SECAM and NTSC frame rates technically apply only to analogue standard definition television, not to digital or high definition broadcasts. However, with the roll out of digital broadcasting, and later HDTV broadcasting, countries retained their heritage systems. HDTV in former PAL and SECAM countries operates at a frame rate of 25/50 Hz, while HDTV in former NTSC countries operates at 30/60 Hz.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In former NTSC countries, what frame rate does SDTV operate at?
Ah, so.. unanswerable

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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where did Eric Scott Raymond fly using a solar powered plane in 1990?
Ah, so.. California to North Carolina

The early Qing emperors adopted the bureaucratic structures and institutions from the preceding Ming dynasty but split rule between Han Chinese and Manchus, with some positions also given to Mongols. Like previous dynasties, the Qing recruited officials via the imperial examination system, until the system was abolished in 1905. The Qing divided the positions into civil and military positions, each having nine grades or ranks, each subdivided into a and b categories. Civil appointments ranged from attendant to the emperor or a Grand Secretary in the Forbidden City (highest) to being a prefectural tax collector, deputy jail warden, deputy police commissioner or tax examiner. Military appointments ranged from being a field marshal or chamberlain of the imperial bodyguard to a third class sergeant, corporal or a first or second class private.

Ah, so..
