Lootnairpawt is only 498m longer than Northolt, so it must have been something pretty serious if the corgi-carrier had to land at Northolt rather than returning to Northolt. If it had needed a long runway, surely Stansted would have been a better choice? Or Brize Norton?
Or was it simply that what the MoD sniffily describes as the 'alternative means' which BoJo was obliged to use was only available at Luton?
A good job the aircraft wasn't carrying HM.....
