This summer I can quite arrogantly state that I will be involved in appropriately 32 fast track PPLs. 98% of which will be completed in 4 weeks or less and all of this will be done in the UK. And this happened last year and the year before that and the year before than as well
Its easy to do even with UK weather when you have the right set up.
Also if you know what you are doing and where to go you can get all of this for 6 grand.
