With regard to the crew it would be interesting to know if the co-pilot was IR - I suspect not. Again, be interesting to know what sort of total and IR time the captain had.
In a conversation I had with the co-pilot he stated that he indeed held an IR.
Thankfully the CAA HOIs of more recent appointment have the foresight to require pilots to use the automatics during tests. The old dinosaurs who apparently saw them as cheating (or too complicated for them to understand), and therefore under no circumstances allowed them to be engaged during test flights, have thankfully retired.
