Partly. Mostly it was not having a clear set of parameters when they started, so every time you turn around top speed and altitude change, until
eventually one side of the team just can't keep up. Both of them changed their top speed and cruising altitude something like 3 times before they even
started building a prototype, but kept the first flight and service entry dates the same until they had to change them.
