The usual reasons for flights being so markedly off-track are either weather (e.g. storms) or conflicting traffic (for example police helicopter operations). It will be interesting to see the reason for today's infringements.
Any updates ? My curiosity is, well........curious! :-)
Just saw a Vistajet Bizjet go by into LHR. Are these all LCY refugees, or simply customers to whom the landing/handling fees are immaterial ?
