"HP Marathon T MK 11 - if you don't know, then Google it!
'Humbly Pudge' may well have laid claim to it in later years, but it was the product, originally, of Messrs Miles, hence the
Marathon titling. You are correct though in its awfulness. I have two flights logged in the beast from Thorney - one with M Plt 'Horse' Adams, who convincingly demonstrated its inabilty to maintain height on three and its breathtaking (unwanted) rate of descent on two! It did, however, have a saving grace - the flap and gear levers were adjacent and easy to misidentify ... the numbers on inventory were thereby reduced fairly quickly!
