No, airplanes (commercial aviation) do not have cameras in the bathrooms, or as they are called, “lavatories”. That would be illegal. If your finger, “touches” the reflection of your finger, it only means that there isn't a layer of thick glass over the reflective material.
TSA does not prohibit photographing, videotaping or filming at security checkpoints, as long as the screening process is not interfered with or sensitive information is not revealed.
Yes, airline pilots can go to the toilet during a flight. In fact, they have their own private lavatory in the cockpit that is separate from the passenger cabin.
Planes have headlights so that pilots can see what is in front of them. Unfortunately, they are only effective during takeoffs and landings. Even with the slight illumination offered by the headlights, only darkness is visible when looking out the front window of a cockpit.
Answer: Some of the larger airplanes (e.g. Airbus A340 and A380, and the Boeing 747-8) have cameras to help assist the pilots on taxiways and at gates. Smaller airplanes (e.g. B737 and A320) do not need them as the flight crew can see the wingtips.
Film can most definitely get altered/damaged by scanners. It just depends on how sensitive the film is. Lower speed film (which is what you used) can handle scans absolutely fine. Even 800 ISO Film can go through a scanner multiple times until you see the slightest bit of fogging if you're lucky.
Planes are required to travel with fully stocked first aid kits. If you need a bandaid, sanitizing wipe, or some basic medications, you can ask your flight attendant if they have what you need. Some airlines also offer sanitary pads and tampons as part of their medical supplies, but you can't count on it.
Of course! Planes are on autopilot for most of the time, and the co-pilot's there if anything happens. The pilot (or captain as they're called) is able to use the bathroom without any issues. Some airlines even opt to have a special bathroom for the crew installed.
Yes, passengers are generally allowed to use the toilet on the plane before takeoff. However, there may be certain instances when access to the toilets is temporarily restricted for safety reasons.
