One Boeing 747 British Airways set a new speed record for a subsonic commercial flight flying between New York and London.
The 9 February flight BA-112 broke the current speed record for a subsonic commercial flight, when making the flight from New York to London in just 4 hours and 56 minutes.
Assigned to this flight was the “Queen of the Skies” Boeing 747-436 G-CIVP license plate with MSN serial number 28850 and with 22 years from entry into service for the UK's leading airline, which, taking advantage of the strong high-altitude wind currents called in English "jet stream", became almost a legendary Aérospatiale-BAC Concorde.
As reported by the portal Flight Radar 24, the previous record was held by a Boeing 787 de Norwegian, which made a flight between New York and London – Gatwick one 5 hours and 13 minutes.
the memory
breaking the record with 17 flight minutes, the boeing 747-400 of British Airways well took advantage of the jet streams to get to its destination faster and also, consume less fuel and thus generating a lower environmental impact.
The flight in question reached a maximum recorded speed of 825 mph o 1,327km/h, What would it mean to break the sound barrier?, but the speed reported by Flight Radar 24 is the speed relative to the ground.
During the record speed flight across the Atlantic, BA112 traveled at a constant Mach 0.86 O 86 percent of the speed of sound. Because the speed of sound is relative to the mass of air in which the aircraft is traveling, the flight does not "break the sound barrier".
Jet stream or jet stream
The jet stream is nothing more than a current of wind at high speed and is found in specific areas of the planet that are not very "width.".
On earth, These currents meet at the tropopause between 9 a 17 kilometers high and the direction of the wind is from west to east (direction deviations may occur) at speeds greater than 180 km/h.
In general terms, The jet streams are classified by polar current, these being the fastest, and by lower velocity subtropical currents, but taller.
