The shortnose was even uglier. Nickname 'The Sled'. Cruised 130kts. Hot & noisy. Pre flight, to check the oil of the centre engine,the pilot opened the 2nd door on the starboard side stepped on the hinge then deftly swung himself between engine cowl & fuselage,until he could clamber up onto the roof. Walking down towards the engine,the C of G would move rearward & the tail would drop about 20cm til it rested on the tail steady,so don't get jolted off. The prop would then be hugged with the left arm whilst the right hand had to feel for the oil panel,then the red hot dip stick,always thinking 'I'm sure I turned off the mags....or did I?''
