Highest commercial decelerator descent

The highest commercial decelerator descent facility is Sky Jump Las Vegas at the Stratosphere Casino, Hotel & Tower, measuring 252 m (829 ft) in Las Vegas, Nevada, USA, opened on 20 April 2010. Jumpers leap off a platform outside the 108th floor of the Stratosphere’s iconic tower at the north end of the Las Vegas strip. The average speed per rider is between 40-50 mph on the way down before deceleration begins shortly before the landing point.

Highest defence budget

The world total for defence spending in 2009, according to the Stockholm International Peace Research Institute, is US $1,531 billion and the nation that spends the most is the United States of America with a defence budget in the order of US$ 661 billion (with for 2010 a projected outturn of US$719 billion) ­ just under half the world total. For 2011, the US defence budget is expected to rise to some US$739 billion.

Highest energy particle detected in nature

On 15 November 1991 the ‘Fly’s Eye’ cosmic ray experiment in Utah, USA, detected an interstellar subatomic particle with an energy of 3.2×10**20 eV (roughly 50 joules or 12 calories). This is roughly the same energy as a fast-pitched baseball. The Fly’s Eye experiment was built and operated by the University of Utah, USA.

Highest flight by solar-powered spyplane (UAV)

On 9 July 2010, Zephyr, a High-Altitude Long-Endurance (HALE) Unmanned Aerial Vehicle (UAV) was launched at 0641hours and set three new world records. They are currently awaiting ratification by the Fédération Aéronautique Internationale and were: The absolute duration record for an Unmanned Air Vehicle of 336 hrs and 22 minutes (14 days and 22 minutes). The duration record for a UAV (in the U/1.c / 50-500Kg category) – time as above The absolute altitude record for a UAV (in the above category) – of 70,740ft Continue reading →
