Kiwi-built amateur rocket reaches space: 'Pretty amazing' (www.1news.co.nz)

A Kiwi-built amateur rocket is believed to have set a record as not just the country's first but one of the fastest launched into space — all with home brewed beer and gin onboard.

Meraki II, a 4-metre long rocket, launched near Arthur's Pass on April 19, reaching a peak altitude of 121.6km.

The two-stage rocket travelled at mind-boggling speeds of up to Mach 5.6, or around 1.9 kilometres a second — fast enough to cover the distance between Cape Reinga and Bluff in just over 12 minutes.

"It's the first successful amateur non-US spaceshot, and the new velocity record-holder"

Mach 5.6, or around 1.9 kilometres a second

One of these numbers is wrong, as the mach number is defined using the local speed of sound, which changes a lot as you go further up in the thinner atmosphere.
