The domain speedtest.net has been used to host a speed test since 2000, and was acquired by Ookla in 2006. [12] As of 2011, Ookla claimed 80% market share and was one of the top 1000 most popular websites. At the time, Ookla derived its revenue primarily from fees paid by companies to license custom speed test and proprietary testing software.
The following is a list of speed records for various types of vehicles.This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category.
The first track to be started onsite was an initial 6 mi (9.7 km) segment of the planned Linear Induction Motor Research Vehicle (LIMRV) test track, built by Morrison-Knudsen; it was anticipated that the initial segment would later be extended to a full 21.8 mi long (35.1 km) oval and a parallel oval guideway would be completed for the Tracked Air Cushion Research Vehicle (TACRV).
A test case was brought by motoring pioneer John Henry Knight, who was subsequently convicted of using a locomotive without a licence.

Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.
The Lockheed SR-71 Blackbird holds the official Air Speed Record for a crewed airbreathing jet engine aircraft with a speed of 3,530 km/h (2,190 mph). The record was set on 28 July 1976 by Eldon W. Joersz and George T. Morgan Jr. near Beale Air Force Base, California, USA.
