These masts can lead to expensive errors..
Loaded mission, launched, Y-6 has flown path before but this time was flying sideways with a lot more power..
Hit Return To Launch
In a flash.. full noise, 30 degrees onto a road, stunning cart wheels.. look at all those flying bits...
Problem - I forgot to lift the GPS antenna mast into position..
But I was able to recover the battery adapter plug/socket.. everything else was munted..
