When Pascal-B was detonated, the blast went straight up the test shaft, launching the cap into the atmosphere. The plate was never found. In a conversation with Bill Ogle, Brownlee estimated its velocity as “six times the escape velocity from the Earth”—approximately 67.2 km/s (150,000 mph).[10] Scientists believe compression heating caused the cap to vaporize as it sped through the atmosphere































Linux (/ˈlɪnʊks/ LIN-uuks)[16] is a family of open source Unix-like operating systems based on the Linux kernel,[17] a kernel first released on 17 September 1991, by Linus Torvalds.[18][19] Linux is typically packaged as a Linux distribution (a.k.a distro), which includes the kernel and supporting system software and libraries – most of which are provided by third parties – to create a complete operating system. Linux was originally designed as a clone of Unix and is released under the copyleft GPL license.[20]
