21 days for a PPL - luxury! When I took my PPL, MEP and IMC at OFT in 2003 they were still offering a VIP 14 day PPL!
Needless to say the success rates in 14 days was low and to even have a hope of achieving this the non-VIPs (everyone else - including me) were regularly bounced from aircraft slots that had been booked. Instructor assignments were often changed.
I like OFT - facilities & location work for me. However, it is not a place to go if you need your hand held and that is true even if you are planning to be there for more than 21 days!!
