A call comes through from Saville's secretary, "Mr Hackenbacker is wanted on the phone". Saville offers the use of this number 3 phone (in a adjoining room). Its Lady Penelope asking Brains for a favour.
The Secret Hackenbacker Device
Brains and Tin-Tin travel to London to watch the Skythrust land at London International Airport.
After the plane had been hijacked, Thunderbird 2 knocks-out the undercarriage with a missile, Captain Ashton tells Mason that they have no alternative but to return to London, were they at least have the facilities to handle a crash-landing. Reluctantly Mason agrees. The aircraft crash-lands at London Airport, but the secret 'Hackenbacker Device' comes into play, a rear-mounted electable fuel pod flies free and is detonated before the plane lands.
Mr Hackenbacker observed the aircraft through binoculars that can be worn on the head like a pair of glasses.
