Songs that have something to do with planes / flying:
Typically Tropical: Barbados
Reinhard Mey: Ueber den Wolken
Don McLean: American Pie (about a crash)
Lenny Kravit: Fly Away
Shawn Colvin: Another Plane went down today
The Beatles: Back in the USSR
(just for the jet engine noise)
Joe Cocker and Jennifer Warnes: Up Where We Belong
Music that, to me, sounds a bit like flying:
most of the stuff by Enya
Karl Jenkins: Adiemus (used for Delta Airlines adverts in Germany 6-7 years ago)
some others I don't remember right now...
About the project: This is just my opinion, but I believe it's perfectly acceptable, as pupil or student, to use photos for homework purposes without getting permission (as long as you give image credit). When I had to give a presentation about my final year project last year, I borrowed images liberally and used them for a powerpoint presentation. Asking each and every one of the photographers for permission would simply have taken too long...
