Why would you fly?• Guarantee to detect the meteors
• able to move under the radiant
• much more meteors visible
• joint efforts of many specialist altogether
• Past European experience: participant to NASA MAC (PI: P. Jenniskens - SETI), 2008 ATV reentry (PI: J. Hatton - ESA)

A joint effort
• 2 aircrafts
• EISCAT radar observation (N. Brosch, A. Pellinen-Wannberg)
• Multiple station in Greece (IMCCE, Armagh Observatory)
• Multiple station in France and Spain (DMS, IMCCE, Pic du Midi), Germany (SETI, DMS), Uzbekistan (NAOJ)
• and hundreds more!

After the campaign...
• Collaboration for data analysis (Ondrejov observatory, SETI Institute, Univ. Lomonosov etc.)
• workshop organizing France in September 2012 (waiting for confirmation)
