Today I discovered my first big screw up (I've had lot's of little ones!). I did not put the inner longeron reinforcements in place before I began riveting. So I spent 4 hours correcting what I did yesterday and only accomplished half of what I needed to get back on track. What a giant pain it is to drill out all those rivets. I need to read the manual a little more carefully from now on. I've been dreading a mistake like this.
