Solar Impulse 2 #First Flight - Maiden Flight Best-Of

So in the planning, when it's 04:05 a.m...(roll-out is at 04:15!)

At 04:05 go take your positions so I can open the door, that's mostly for people under the wings.

Just so you know, we will do the roll-out
before we get the GO signal from the Flight
Test Team.

This means when we'll
will go out we may ear "No, you must come
back"

... But still 90 per cent chances they tell
us we're good to go on!
