"Whilst this would be considered a promising start for any new business, Thomas Cook Airlines still represented the majority of our revenue and made it impossible for us to sustain operations." The MRO unit highlights its parent company's "wider work across the aviation sector" and says this "continues to thrive", adding: "Morson remains the largest technical recruitment agency in the UK and Morson Projects a significant provider of design services, including EASA Part-21J services." Morson Aircraft Engineering Services' customers included Thomas Cook Airlines and Virgin Atlantic – both of which had already been Monarch Aircraft Engineering clients – alongside Air Transat, Avion Express, SmartLynx and Sunwing Airlines.
