Lost iPod Classic Silver on flight from Dublin to Amsterdam last fri 29.01.2016 EI 610 17:00

I dropped my i Pod during take off. Could nt find it under the seats. Had a good look with staff when we landed, no joy. Hope someone may have picked it up. 10 plus years of music, books, recordings, pod casts are on this device. Much of it not backed up. Also some work and study material plus very important audio therapy material. On top of all that it has very sentimental value !!!! Substantial Reward Offered. Thank you for any help, Cormac.
