Speed Of A Bullet

Was just curious and found out that normal
bullets are capable of flying between the range
of MACH2 - MACH4 with the optimum being at MACH3.

Fastest approaches to delivery of objects have
been using electromagnetic rails which can go upto
MACH 9.

Aircraft Engines

Was recently reading a
very nice post on different types of
aircraft engines. Currently there
are only one type that are capable
of carrying out supersonic combustion..
the Scramjets... These rely on
having no moving part and achieve
basic accelaration by the use of
booster rockets.. Such machines have
been tested to achieve max speeds of up to
Mach 9
