Odd departures
Many many years ago when the French were being even more impossible than normal. A Britannia 737 got stuck at Manchester and was required at East Midlands, couldn't get a slot between all the tightly packed traffic from EDI, GLA, NCL etc so the ferry went special VFR not above 1,500' out of the TMA, bet the crew were still grinning at Castle Don.
Be lucky
