You fly on aircraft operated by US based airlines whenever possible. Practically, you cannot break down the cockpit door. If you could, you'd have to worry about hijackers doing the same thing.

Practically, you cannot break down the cockpit door. If you could, you'd have to worry about hijackers doing the same thing. So, to avoid a Germanwings situation you want an airlines whose general policies mirror FAA regulations.
According to the US Federal Aviation Administration, doors should typically be tough enough to withstand a grenade blast. They are usually left locked throughout the flight. Cockpit security systems are supposed to allow a pilot the ability to access the cockpit.
Under this program, flight crew members are authorized by the Transportation Security Administration to use firearms to defend against acts of criminal violence or air piracy undertaken to gain control of their aircraft.
However, a recent NTSB study concluded that glass-cockpit aircraft were no safer than conventional instrumented aircraft. Disadvantages of traditional analog instrumentation are the multitudes of mechanical components: gyroscopes, delicate flywheels, gimbals, seals and motors.
This happened on British Airways Flight 5390 in 1990. An engineer had sight matched a retaining bolt on the windscreen and it blew out as the plane climbed through 17,000 ft. The explosive decompression pulled the captain halfway out of the broken window, and his clothes caught on the flight controls.
If an aircraft cockpit window were to break while the aircraft was at cruise altitude , you would experience rapid decompression which is extremely dangerous to all on board . The pilots would immediately put oxygen masks on for safety and the oxygen masks in the cabin would be deployed.
At least with U.S. military or the U.S. produced Chinook cargo helicopters ( other countries buy/use them) bulletproof glass does not exist in the cockpit. The only protection pilots have are armored seats in the cockpit.
So up in the air, the aircraft's door is pushed into place by a force far greater than what you and I will ever be able to overcome by muscle force. Therefore, to answer your question, no – the doors can't accidentally be opened in flight.
Part of the reason glass cockpits are still relatively rare in general aviation is obviously cost – $30,000 is a lot to spend on avionics when the airplane is only worth $40,000. But that is beginning to change, with new products from Garmin and Dynon pushing the price down below $10,000.
No they are not, at least not fully. There have been instances of equipment failure caused by coffee spills, resulting in the need to abort the flight.
Airline pilots can be exposed to the same amount of UV-A radiation as that from a tanning bed session because airplane windshields do not completely block UV-A radiation, according to research. Airplane windshields are commonly made of polycarbonate plastic or multilayer composite glass.
While air marshals aren't on every flight, they are authorized to fly on planes of any U.S. air carrier, Maryville University says. However, the 2020 GAO report notes that air marshals are not allowed to fly on planes of foreign flagged carriers, or airlines based in other countries.
In the event of a hijacking, the pilot should divert and land the aircraft at the nearest suitable airport, where controllers can prioritize its landing and provide necessary assistance.
The federal air marshal program continues to be alive and well in the United States. There are only believed to be at most a few thousand people employed by FAMS, and many of those people don't even fly. So while there continue to be air marshals, it's estimated that fewer than 1% of flights have these people onboard.
