I initially started my PPL training in Biggin Hill back in 2008.
There were times I would go months without flying thanks to weather, until finally after 2 years my flight school went bust, 35hrs or so in.
Worst part was I paid for the full course, and lost a fair amount of money in the process.
Now picking up my training again at Headcorn, and so far no cancellations (and paying as I fly!)
