Blue-green algae produce two toxins, each with different symptoms. Signs of neurotoxin poisoning usually appear 15 to 20 minutes after ingestion. In animals, symptoms include weakness, staggering, difficulty in breathing, convulsions and ultimately death. In humans, symptoms may include numbness of the lips, tingling in fingers and toes, and dizziness.
Aeropro imposed the weight limitation so that the aircraft could comfortably meet ASTM stall speed requirements (a maximum of 51 mph) for Light Sport aircraft. The Aerotrek stalls at 43 mph indicated airspeed with flaps down and 49 mph with flaps retracted. Trim and flap levers (left inset) are easy to reach. The trim is the shorter lever, while the longer flap lever moves through its full range without detents.
Guinness World Records recognized NASA's X-43A scramjet with a new world speed record for a jet-powered aircraft - Mach 9.6, or nearly 7,000 mph. Answer The fastest speed wasâ¦ recorded by an unmanned aircraft called X-43. It can reach the speed of almost 7460 miles per hour. The fastest manned aircraft is X-15. Its top speed is 5115 miles per hour. This is very, very fast. Different ways of flight propulsion must have different categories as fastest in their method of power, to allow for this question to be answered properly. However, the overall fastest flight reached is Mach 9.8, which is about 12,144 km/h.
