Hi All,
On most 737NG's I've seen, the ground spoilers will deploy to their respective angles, (52/60 degrees, quoted from The Boeing 737 Technical Site (http://www.b737.org.uk/flightcontrols.htm#Spoilers_/_Speedbrakes)) and stay there until selected otherwise.

This seems to be the norm except for;
I've noticed on most Thomson aircraft that the ground spoilers extend to a much larger angle than most other 737NG's.
In this video (Jetairfly, but demonstrates the same effect) you can see the spoilers deploy to a much larger angle, but then retracts to what I consider(ed) to be normal, at presumably a speed such as 60kts.

Any ideas why there is a difference in operation between (seemingly) operators, and how this change can be affected from the flight deck.
