The Bolero leg attempted by The Lost Squadron on July 15, 1942, was Bluie West 8 [BW-8] to Reykjavik. BW-8 would be the equivalent of Sondre Stromfjord. There were a variety of bases that were used in Operation Bolero during the movement of planes in World War II. The modern day Bolero 2 mission is delivering Glacier Girl to England using a combination of legs that does not match the ones used by 1st Fighter Group, 94th Squadron, B Flight in July 1942.
It is my understanding that B Flight arrived at BW-8 via Bluie West 1 (BW-1 near Narsarsuak, Greenland) and Goose Bay.
The Goose Bay to Frobisher Bay leg (which will be attempted again on 06/26/07 - weather permitting) was not used by The Lost Squadron.
When The Lost Squadron encountered weather approaching Iceland on July 15, 1942, they began a return to BW-8. Later they learned that BW-8 was closed with 1000’ ceiling an 1/8 mile visibility. B Flight then attempted to reach BW-1 but ran out of fuel after 8 1/2 hours. 2 B-17s and 6 P-38s performed emergency landings on a Greenland icecap. The crews were rescued (no casualties or severe injuries) about a week later. However, the planes were abandoned except for a mission to retrieve the then top-secret B-17 Norden bomb sights.
Edit – Here’s a link to an ABC News video that does a decent job of telling this story.
