The Steep Rock "hoax"

Here's a UFO tale said to be a hoax, and who am I to dispute that:

What shows this UFO account to be a hoax?

On its face, the account is fictive -- novelized -- as if someone was writing a SciFi story. (Compare it to Lonnie Zamora's police-like report about his 1964 Socorro sighting.)

But what disturbs, somewhat, are later "sightings" like this one which I've noted here: The Aldeburgh sighting and the Reverend Gill sighting(s).

Was the Steep Rock acount actually a hoax or did the persons initially reporting it recant, bcause they were hounded by peers or government/military agencies, who wanted to discount the sighting (for one reason or another)?

Yet, the prose elaboration tells me the story was concocted, however....
