Series of 10s Moor Walk #4: Memorial Visit?
This is the 4th in a series of 9 caches (8 caches + a bonus final) along a 9km 'circular' walk which, allowing for caching operations - and taking in the awesome scenery, photos, bird-watching and refreshment stops - should take around 3-4 hours.
For background info on the series and parking waypoints, see GC2V7T8 Series of 10s Moor Walk #1: Intro & Start.
The cache, a large food container with a smaller one and a 35mm film canister containing the log paper inside is hidden alongside a drystone wall running roughly south-east from the Addingham Gritstone escarpment at Windgate Nick.
Direct approach: continue west along the trail from #3 as far as the trail junction @ N 53° 55.205 W 001° 53.528 just south of Windgate Nick, turn south here across to the wall, then follow this for some 350m along its north side to GZ.
Approach via Viewpoint Bench and Air Crash Memorial: continue west along the trail from #3 as far as N 53° 55.196 W 001° 53.738 the location of a wooden bench where you can spend a few moments taking in the stunning view north to Addingham, up Wharfedale and to the moors of the Yorkshire Dales.
The deep track at Windgate Nick has been created by centuries of use as the only route linking Addingham with Silsden and the Aire Valley, passing by the Doubler Stones, Elizabethan coalpits, and 14th century iron working sites in Silsden.
'Johnnie Grey', describing this walk through the Nick from Silsden in 1891, wrote: ‘A view of Arcadian loveliness bursts upon the vision, rendered all the more captivating by its complete suddenness. Wharfedale is now revealed in grand array’.
Nearby is a stone pillar memorial commemorating the tragic 21:00 on 22/3/43 crash of a 25 Squadron deHaviland Mosquito Mk II DD750 in which the pilot and navigator were killed . . . due to critical errors by ground crew.
The plane was returning to base at Church Fenton after a ‘Ranger’ operation cancelled due to bad weather. This is where night-fighters flew lone very fast and low hit and run strikes deep in enemy territory.
The squadron had been using a forward base of RAF Coltishall (nr Norwich) and 3 aircraft took off from there to return to their base at Church Fenton (SW of York) that evening.
On nearing Church Fenton this crew contacted base to state their intention to land but were told to delay landing and await their turn in the airfield circuit.
Sadly, they were given the wrong height and coordinates for their holding pattern.
The aircraft flew at speed into high ground east of 
Sildsen at night in low cloud conditions. Flying roughly north to south, it appears to have clipped the top of the escarpment at Windgate Nick and crashed onto the moor behind somersaulting, bursting into flames and spreading wreckage over a wide area before coming to rest against a drystone wall dividing a field and White Crag Plantation at approx. N 53° 55.092 W 001° 53.786 some 200m south of the memorial (which has an incorrect date for the crash). See here for more details.
