The HS125 was also called the 'pocket rocket'
And the SC7 (Skyvan) - not really a 'big' aircraft, was called 'Melody in Metal' and 'The Whispering Nissen Hut'
The Bristol Britannia was called the 'Whispering Giant' - was very quiet for such a big aircaft.
The A380 will probably be called 'The Dinosaur'!
