No fear for any plane because this is a sim and I will be able to walk away after every single crash.
Trying to perform unusual manouvres is a different cookie.
For example: flying through a hangar without being very sure that the backdoor is opened is a bit scary ( near RW31 at JFK for example)
If succesful you’d receive a phone number to call immediately I guess.
Regarding the F-104: I had the opportunity to sit in the cockpit of one in a museum at EHTE and was amazed… How in heaven is it possible to get this chimny in the air, do your thing and bring it back without reaching the breaking news headlines in a negative way…( scratches, or even worse: total loss of hull and a funeral)
