The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
[7] [9] It is the fastest object ever built on Earth. [10] The project was announced in the fiscal 2009 budget year. Johns Hopkins University Applied Physics Laboratory designed and built the spacecraft, [11] which was launched on 12 August 2018. [2]
Sep. 27—On September 27, 1956, Captain Milburn Grant "Mel" Apt became the fastest man alive during his test flight aboard the Bell X-2 supersonic aircraft, reaching speeds three times faster ...

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.
MW 18014 was a German A-4 test rocket [nb 1] launched on 20 June 1944, [1] [2] [3] at the Peenemünde Army Research Center in Peenemünde.It was the first human-made object to reach outer space, attaining an apogee of 176 kilometres (109 mi), well above the Kármán line that was established later as the lowest altitude of space.

Team USA's Noah Lyles took the gold in the men’s 100-meter final at the Paris Olympics — by five thousandths of a second. Lyles, who won Sunday with a time of 9.784 seconds, came out just ...
The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [2]
