Update: Midnight BST (2300Z) Tuesday (Day 4)

The Swiss race ahead, the rest bide their time

The SWI2 Swiss team of Kurt Frieden and Pascal Witpraechtiger continue to dominate this race, as they head across Serbia at a height of 14,000 feet and a speed of 31kt. Their prediected trajectory puts them landing towards the east of Romania or Moldova sometime on Tuesday evening.

Congratulations to the Swiss team on passing the 2000km mark.

The other remaining teams are trying to time their arrival time at the Italian coastline such that they are around 5nm from the coast 30 minutes before sunrise. They can then pass over Italy and start to chase the Swiss.
