Nostalgia!
Thanks everyone for the replies.
Yes, the memory sometimes plays tricks with the details, and I'm sure that all the stories involving D H-H have been altered and embellished over the years!
I met him again at AOTS Oxford doing my CPL/IR and ATPL Ground School. He had not improved with keeping. Sadly, he had befriended a gentleman who held an authority to deal in explosives. As a result of this, D developed an addiction to the Lifeboats' 'Dull Boom Maroon', a series of which were detonated at various hours of the night outside (or maybe even inside) Mitchell Hall at OATS and in Main Street, Kidlington and Woodstock. He was last heard of living on Scone Airfield in an old farmhouse. He flies from Scone testing other peoples' homebuilts. I told you he was mad!
Studefather: Wow, what a wonderful offer. I will certainly try and take you up on it. But I insist on paying for the Avgas and breakfast. I'll bring an extra little bottle to fill so I can fuel my Zippo, and sniff the fumes when I'm feeling extra nostalgic!
