Longest flight for a micro unmanned aerial vehicle (UAV)

On 4 November 2007, a new distance record was set for a micro-unmanned aerial vehicle (UAV) in Lancaster, California, USA. The “Pterosoar”, a joint project between Oklahoma State University and California State University (both USA), flew 120 km (74.5 miles) consuming only 16 of the 64 g of hydrogen carried on board in a pressurized hydrogen tank. Potentially the UAV could significantly increase this distance to nearly 500 km (310 miles) based on its fuel capacity.

Longest flight by solar-powered spyplane (UAV)

Zephyr is a High-Altitude Long-Endurance (HALE) Unmanned Aerial Vehicle (UAV) made of ultra-lightweight carbon-fibre. It flies on solar power generated by amorphous silicon arrays covering the aircraft’s wings, no thicker than sheets of paper. It is powered day and night by rechargeable lithium-sulphur batteries that are recharged during the day using solar power. On 9 July 2010, Zephyr 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 Continue reading →

Longest fishing rod

Longest fingernails (male) – ever

The longest fingernails on a pair of male hands belonged to Melvin Boothe (USA) whose nails had a combined length of 9.85 m (32 ft 3.8 in), when measured in Troy, Michigan, USA on 30 May 2009. Unfortunately, Melvin passed away in December 2009. Melvin’s nail measurements were: Right Hand: Thumb: 39 3/8 = 100 cm, Index: 37 1/4 = 94.6 cm, Middle: 39 1/2 = 100.3 cm, Ring: 40 1/8 = 101.9 cm, Little finger: 34 5/8 = 88 cm. Left Hand: Thumb: 45 Continue reading →

Longest fossil record

Stromatolites have the longest fossil record of any form of life on Earth. These cauliflower-shaped, rock-like structures are formed by the activity of cyanobacteria and appeared on Earth as early as 3.5 billion years ago. In 1954 a colony of living stromatolites was discovered in Shark Bay, Australia, with forms similar to those from the Precambrian era.

Longest forward jump flip / somersault (parkour)

The longest forward jump flip is 5.8 m (19 ft 2 in) by Richard Barnes (USA) at Southlake Gymnastics Academy in Southlake, Texas, USA, on 18 July 2010. Barnes attempted the flip on an FIG competition-certified tumbling floor. Included among the witnesses were former NCAA Division 1 gymnast Shannon Prince, 15-year gymnastics coach Eric Barnes, 5-year gymnastics instructor Amanda Solomon 18-year fireman Darren Burkhart. Barnes had attempted this record previously and failed for using his hands to stabilize his landing on the floor, a correction Continue reading →

Longest Formula One circuit

The longest circuit by lap distance to host a Formula One World Championship race was the Pescara Circuit, which hosted a race in 1957, when the road course measured 16 miles (25.8 km). Sections of the circuit ran along a cliff edge, and other sections were hilly, leading many experts to contend that Pescara was the most dangerous F1 track of all time.

Longest footbridge

On 3 October 2009, the 2.06-km (6,767-ft, or 1.28-mile) Poughkeepsie Bridge (also known as the Walkway Over the Hudson State National Park) in New York, USA, was re-opened to the public as the world’s longest pedestrian bridge. Hornibrook Bridge across Bramble Bay in Queensland, Australia, was longer but demolition started in the summer of 2010.
