Lets start this again then....BA088 FROM NBO (Yes planes are capable of flying from NBO to London nowadays and yes....Luton is considered a London airport SHOCK HORROR) has indeed diverted to LTN as a result of some incident...even proven on the BA website that the flight landed at 1633 into Luton and subsequently cancelled!!!!
Now the only info I dont have is to why this happened and I was kinda hoping someone out there in pprune world may know as you lot are always normally so sh1t hot on incidents like this!!!!
