The UFOs presented in this story do not look particularly like the ones seen in the TV series. The design looks more like a mushroom or a muffin!

On page 2 of the story, the SHADO agent who enters the UFO appears to be carrying a laser gun of some kind. Straker and Freeman wield the same guns on page 6. Normally SHADO agents are seen with fairly conventional projectile weapons.

This story reveals the Whitehall liaison to SHADO is Sir Frederick Markham. Whitehall is a road in Westminster, central London, where the seat of the UK government is located.

Straker meets Sir Frederick at Crofton Air Field. As far as I can tell, this is a fictional air field in England. Of course, the narrative does refer to it as a secret research establishment.

Dr. Lisman presents Straker with a remote-controlled hunter-killer device to use against the aliens called Tin-Can Tommy. The four small wheels on it don't make it look like it could cross rough terrain very easily. And it must be extremely heavy for its size, as Freeman is unable to tip it over by ramming his body into it on page 7.

Tin-Can Tommy is shown to be nearly indestructible when it survives the self-destruction of a UFO.

After Straker temporarily stops the renegade Tin-Can Tommy by covering its sensor windows, why don't he and Freeman stop Markham from shouting to the neighborhood houses that it's safe to come out now? Realistically, the area would not be considered safe for civilians until the device has been permanently deactivated, or, better yet, removed from the vicinity.

UNANSWERED QUESTIONS

It seems that a number of civilians living nearby saw the UFO land in their neighborhood. Will SHADO use the amnesia drug on them to make them forget?
