And a tad louder with four Conways!
Absolutely right spekesoftly all 84000 lb's of them. The 1-11 did have Speys of between about 10300-12500lb's..... No contest
Strangely enough the Caravelle was rated as among or if not the loudest of that era and was kitted with 12600lb Avons and later JT8D's.
Music to my ears
