Denmark may seem a mere stone's throw away from Nordic neighbour Finland, but with volcanic ash grounding flights across Europe, Finland's president was forced to take the scenic route home Friday. President Tarja Halonen was travelling 'by land and sea' to get home after a visit to Copenhagen for the birthday celebrations of Queen Margrethe, who turned 70 Friday, the president's spokeswoman told selfnews. 'She is on her way to Finland and will be home tomorrow,' Eila Nevalainen said, adding that the president's future travel plans were being evaluated in light of developments in flight restrictions caused by massive clouds of ash from an Icelandic volcano. Halonen is due to travel to Poland on Sunday for the funeral of president Lech Kaczynski, who died along with other senior Polish dignitaries Saturday when his government jet crashed in thick fog in western Russia. Nevalainen declined to speculate whether or not Halonen would travel by land and sea to get to Krakow for the funeral if flying was not an option. Finnish authorities have said commercial flights would be grounded at least until 3:00 pm (1200 GMT) Sunday. lv/nl/mb
