F1 is correct; rocket science.
However, if its a film or even a news report, I wouldn't let a bit inaccuracy put you off, after all the general public paid good money to see Die Hard 2 and the Airport series and those were rubbish; Cone of confusion still the best except for The Battle of Britain and Dave Perrin Man in the Sky of course.
BTW is it 55 yrs from now or now from 55yrs ago? If its the later, they might have Doppler Nav and an ADF where, provided the geography hasn't changed too much, they could find a suitable place to let down and continue visually to a suitable airport and throw themselves on the mercy of the authorities for having out of date charts. Is it a short film?
No expert on film matters obviously, but as a gambler I would get Nick Parks to do it in plasticine if you want an Oscar!!
