One thing I've picked up on and that's from their blog... http://feastbowl.wordpress.com/category/events/airshow/ though posted back in May was that the
Lindstrand HS110 Hot Airship which will be flying before and during the interval display.
Does this suggest a genuine 2 part display, to accommodate early departures/Late Arrivals with the airship tootling about in-between?
From that same blog Entry the Great War Display. SE5a and Junker CL5. are to be in attendance.
THe more recent Blog are from Tiger Moth Pilot David Cyster and about the on the ground activities.
What this now gives is...
RAF Red Arrows
RAF Hawk Display
RAF King Air Display
Royal Navy Sea King
Great War Display Team (2x SE5A 2x Junkers CL1 from own site)
RNHF Swordfish (own site confirms Sea Fury as well)
OH-6 Loach (Own website now states Flying Display)
SWIP Team Twister Duo
Looking better all the time.
