I was on 16 at Laarbruch during the transition time from parking the Buccs outside or in the Hangar overnight to parking them in the HAS’s – not allowed to call them Hangarettes! There were times when the Aircraft had to fly in weather you experienced Nutloose. However, after being parked outside in such conditions and as taxying commenced, there were a couple of occasions the weather gave rise to the sight of a uniform spray coming out all along the slits from the leading edges slats as ‘blow’ (BLC) was selected on. Looked really good for the short time it lasted.
