Yes, G-AYTF was maintained by BHL FTS, went to Hickstead a couple of times where the machine was housed in an old barn with rails going out to a platform on wheels for landing on. Douglas once had an engine failure and landed in a sewage farm near Worcester Green near Epsom, you can imagine the language when he told what he had landed in. The engine compressor had failed through corrosion, I am sure that that incident initiated the 600 hr physical inspection of the compressor mandated by the CAA and more frequent compressor washing.
