The flight didn’t get off to a good start when the second dropsonde released from the aircraft failed to give any data until it was nearly at the surface. The third did the same, as did its replacement released shortly after. The entire flight had been planned to be flown at a height of between 26,000 – 29,000ft, dropping sondes as we went, so malfunctioning dropsondes spelt disaster. As dropmaster Stu hypothesised that there could be a problem with the entire batch of dropsondes, the scientists on board considered their options. Plan a) go home; plan b) descend to low levels and use the instruments on board the aircraft to collect data on the barrier winds and lee cyclone or plan c) try one more dropsonde to make certain. In the midst of this chaos, dropmaster Stu had a brainwave – to unpack and then repack the parachute for each dropsonde before launching it. Problem solved, and panic over, we carried on the flight track dropping sondes as planned.

Flying north-west, we eagerly waited for our first sighting of Greenland. This came 114nm from the coast, spotted by our pilots Alan R and Steve, and mission scientist Nina. The rest of the crew had waited impatiently for the last dropsonde to be released, and the seatbelt sign to be switched off before running up to the front to have a look. The scenery was stunning, and there was much photo-taking as we flew NE along the coast for twenty minutes, before being again confined to our seats and the aircraft turned away from Greenland, to finish the flight.
A surprise was in store for project leader Ian Renfrew after everyone had returned to the hotel after the flight. His attempts to conceal his birthday had been thwarted by his wife, who tipped off the GFDex crew! The birthday cake and wine, enjoyed by all, were in no danger of attracting the other guests at the hotel, who scared away by our tuneful rendition of ‘Happy Birthday’ to Ian. The celebrations were reluctantly called to a temporary halt, in order to complete some flight planning, before being continued in the evening at the local fish restaurant. Happy birthday Ian!
