In 2004, an expedition of students from the IGN's school (formerly ENSG, now Géodata Paris) attempted to reach the summit of Mont Blanc but did not succeed.
Notes on verification
Primary IGN article explicitly confirms the claim; independent bibliographic record corroborates the expedition's existence and timing, but the full text detailing the failed summit attempt could not be directly accessed.
