In Minnesota, brown trout 250-380 mm (10-15 in) long and 1.6-2.5 kg (3.5-5.5 lbs) are fairly common in streams. Stream browns over 635-mm (25-in.) long and 5.5 kg (12 lbs) are rare, but in Lake Superior they are often bigger. The Minnesota state record for this fish is 7.56 kg (16-lbs. 12 oz).
Since jets take off at a particular airspeed, the ground speed they need depends on the prevailing winds. Suffice it to say, a 737 rotates at an airspeed of around 130 to 150 knots, depending on weight (among other factors), and an A380 rotates somewhere around 140 to 180 knots.
Hypersonic travel moves a step closer: Orbital and Nasa 3D printed scramjet engine part survives critical wind tunnel tests. 1  This test could lead to planes that can travel 3,425mph (5,500km/h) 2  Orbital's new combustor design could only be made using 3D printing. 3  This is because it has complex shapes that ordinary tools can't handle.
