"In a process called transplicing exons of one gene can be found on multiple chromosomes"
This is a sufficient but not a necessary condition. Trans-spliced genes can have exons from the same chromosome - either from a distant site (as is common in C elegans), or from the same region

You can get the GFF3 from FlyBase:
http://flybase.org/reports/FBgn0002781.html
(but it may need "re-stitching, as the translation to GFF3 may lose some information)
