The Saab 340
Despite this proudly Swedish aircraft still being in operation nowadays, there are so many former passengers of the Saab 340 who swear that it is an absolute horribly painful racket being aboard ever created. The engine is just phenomenally deafening, which is odd given how polite and reserved Swedish people are!

The MD-80
In some cases, an airplane can crash various times, causing hundreds of deaths, and still be in operation! The MD-80 is one such terribly designed aircraft that is sluggish, unfeasible and highly cramped. These downfalls have not stopped Delta or American Airlines from scrapping the airborne terror!
