That works, of course. But there's no particular reason to use Tails, since you're staying offline. Tails is only different from other live os'es when using it online, any live os would work for this purpose.



Or just use a USB based CD drive. USB flash drives are susceptible to their own class of malware, CDs are a better tech if security is the aim (CDs can be made read-only)


Also, if you're already feeling paranoid, burning USB drives (or computers) in your back yard (or anywhere) could make you feel worse. And also make you appear a little suspicious to anyone who notices you doing it.
