If you fly in remote enough areas (outside of the post-9/11 security perimeter), the planes are still open to the cockpit. Sometimes it feels like I'm flying the plane from Indiana Jones and the Temple of Doom with the chicken in the cabin with me. The pilots are indeed often hilarious.
You can, but if you need correction you have to bring a spare pair of glasses with you to avoid this exact situation. Military pilots do need perfect vision
Is that really irony or coincidence? I guess one would hope/expect the "eyes of the plane" as pilots are in good shape, so a bit eyeronic, but seems like a Meredith Brooks-type usage.
