Company tie ups
Tom100 and Yeo Valley / Jet2 - Fowler Welch
Strictly speaking Jet2 developed from Channel Express Air Freight which was a separate subsidiary of the Dart Group who also owned Fowler Welch. There is a good history of the Dart Group and Channel Express going back to Carpenter's Air Services on the Fowler Welch website. The group loved their Heralds so much they named the company after the engines.
