Kiddies,
I think as it was breifly mentioned - it is quite possibly, more than likely, a timing issue to ensure the airframes are flying, and not pissing blood sitting on the tarmac. Big picture, short words, big letters. Look at moi, look at moi, stop focusing on yourselves for a change - being pilots I know, it is all about moi - Kimmy. But an aircraft on the ground costs money, and eventually jobs - been there done that. So take a breath, and wait
