Mystery building on airfield in Whirlwind footage

I have viewed the film sevedal times and am inclined to Warmwell as the location. The opening shots show the line of aircraft facing a road running parallel with a wooded area. The west edge of Warmwell had this feature. Warmwell was, at one point, an Armament Training School. A gaggle of Whirlwinds is shown dropping GP 250 pound bombs in level flight and Warmwell had a bomb store whereas Ibsley did not. There again, many of there record films had unrelated shots spliced in!

If it is Warmwell then the low flying aircraft in your structure scene must be flying directly south with the airfield hangars in the southeast.

The quality of the film is poor and the unidentified structure indistinct yet appears quite tall and therefore hazardous to low-flying a/c.

Water tower?
