Re: L1 Build - Upgraded Loc IV

Congrats on the L1 :) .

Re: NSWRA - Mullaley Launch Photos - 6th/7th April 2019

The university team has face shields for when handling any energetics. They have them in preference to safety glasses. I am not going to disparage my team if they are keeping themselves safe. Good work everyone :) .

Here is a pic of the edges with a layer of 107gsm glass with JB Weld. This is more than capable of sustaining the total temperature and pressures expecte...
