To be pedantic only one of Sumburgh's runways has sea either end, I was there 1989-91 and the fire men could still tell horrific stores of the Danair 748 and BA Chinook!! The co-pilot of the Chinook was still flying S61's at LSI and did a mean curry night at the Sumburgh hotel!! Biggest jet in my day was Maersk B732 diverting in from Faro with gravel kits on, only saw them use 15/33 mind you!
Sorry ramble over carry on......
