It's probably got nothing to do with Shapps.

They've been jamming navigation signals in the Baltic area for months now. It would be surprising if they stopped for him.

@notsoloud @AE4WX @w7voa That would be my default assumption–GPS jamming in that area isn't constant, but it's been common for the past few months, so I would start by assuming it's coincidence. There are people who have a better idea of the typical pattern of jamming who might be able to say if this was typical. But first, we need the flight data–Does anyone know the aircraft or when it was flying?
