You don't need a light inside the airplane, just hit your head on the overhead bin or tv monitor and everything will light up With stars!! I happily pocket carried a Fenix LD21 for 3 years and it disappeared recently. SAD!! Currently trying the Streamlight PROTAC 1L-1AA and I'm not reall excited with it using AA batteries and the body itself is slick and needs some texture. Much better with lumination with CR123's but a bit spendy and still has a slippy light body. Gonna run over to Fenix on Main st just south of 81st in BA and check out something different and just see what they have.
