Question: is pelican 1560 carry on?
Answer: The 1560 is technically too large to be a permissible carry-on for most American domestic airlines at about 22 x 18 x 10.5 (the Pelican 1510 and new 1535 are carry-on legal: 22 x 14 x 9 is typical carry-on size), but I've never had a problem rolling it through security in dozens of trips.
