LEX is a drop down test from 3 Kms. It is to study the landing characteristics of the lander. It is not an orbital flight. The next one REX is for studying reentry after an orbital flight. (HEX was to validate launch and suborbital hypersonic reentry). The last in the series will be the most challen...

Re: Naval LCA - News and Discussion

You aim for 2 wire as if you aim for 1 and fall short you have high chance hitting the deck with your sngl of descent. 3 and 4 are for redundancy. This is a standard aircraft carrier practice. You hit the wire but accelerate for take off in case the arrestor cable breaks.

Re: Naval LCA - News and Discussion

Typically engagement of the second wire is aimed for in carrier landings. Trapping the first wire is not considered ideal. 3rd wire is also a near hit miss during post flight debriefing.
