The character was originally devised by the production team to do any action scenes required in episodes when they had envisioned that the new Doctor would be played by an older actor (Sarah-Jane even jokingly compares Harry to James Bond at one point). When forty year-old Tom Baker was cast, however, this was no longer a concern and the decision was taken to write Harry out — something producer Philip Hinchcliffe later admitted was probably a mistake, as Harry was a likeable and popular character who worked well with both of his fellow leads.
Harry's last regular appearance is in the season thirteen opener "Terror of the Zygons", which had actually been made at the conclusion of the twelfth production block and held over to start the following season. At the conclusion of this story he chooses to return to London by train rather than by TARDIS with the Doctor and Sarah-Jane, who continue their adventures without him. He does, however, reappear three stories later in "The Android Invasion", both as the original Harry and an android double. This is the character's final appearance in the programme.
A photo of Harry can be seen in Sarah-Jane Smith's attic in "The Sarah-Jane Adventures" and in "Invasion of the Bane", Sarah-Jane thought of naming her newly adopted son after him before deciding on Luke.
Fire drill
A fire drill is a sudden practice event, where people leave a building. They are practicing what they would do if there was a fire in the building. The event is started when the fire alarm goes off. The fire alarm sound can either be a continuous metal bell, a horn or a two-tone siren. Some old alarms in the UK like the Chloride Gent Warbler will curve between the two tones. The entire building is evacuated and everybody leaves the building using the nearest fire exit. At a school, college or university, the teacher or the lecturer counts the people outside to find out if anyone is missing. Sometimes people are evacuated when a drill is not scheduled by the school. This is called a false alarm. There are rules and regulations in place where fire alarm devices should be tested on a weekly basis. If the fire alarm sounds and the building is not evacuated, this may be due to the a scheduled fire alarm test that people already know about.
In the United Kingdom, the law recommends that all schools must do a fire drill every term. But with the current UK government laws, any organization in the UK should conduct a fire drill once a year. In addition to sounding the fire alarms for regular fire drills during term time, regular health and safety checks such as testing fire alarm systems and fire extinguishers must be done weekly. During half term holidays and breaks, these tests are often done during the day so that staff who work during term time know what the fire alarm sounds like. The fire alarm in the United Kingdom sounds either a continuous two tone buzzer or a beep similar to an electronic game beeping in test mode. Sometimes depending on the sounder used, the buzzer can curve between the two tones. In the United States, different states have laws that say how often schools must have fire drills. For example, in many states, schools must have one fire drill per month and fire alarms can either be continuous, or set to different codes such as code 3.
Fire drills commonly take place in schools, colleges and public companies. In public transport such as cruise ships, it is called a muster drill. Fire drills aren't done on airplanes, but a safety demonstration that shows the emergency procedures of the aircraft is done instead. If an aircraft is about to perform an emergency landing, the passangers on the aircraft are told to take the safety brace position on hearing the "brace" command.
During fire drills, some schools block exits with a piece of cardboard or something else that is supposed to stand for a fire. This makes people practice finding another way out of the building.
Fire alarm
A fire alarm is an electronic sounder or a bell. The alarm makes a loud, high pitched sound to notify people that there is a fire in the building. The sounders can be programmed to sound different tones. Most fire alarm sounders in Europe sound like a siren. The bell makes a continuous ringing sound.
There are also companies like HST Fire and KKmoon which produce fire alarms and pull stations. In every building, the fire alarms are hooked up to a main control panel, which allows the inspector or janitor to preform fire drills, do inspections on pull stations, and more.
Some examples of companies which make fire alarms are Wheelock, Simplex, Edwards, Gentex, Johnson Controls, Fire-Lite, and Notifier(Fire-Lite and Notifier both being owned by Honeywell). There is also Fulleon who are best known for their Roshni electronic sounder. These sounders are often used around Europe and they have 32 user selectable tones. Sometimes, old-fashioned fire alarms are metal bells. Many fire alarm systems also have flashing lights, also known as strobes. These are important for deaf people who cannot hear the fire alarm. There are also special alarms which are less loud for sleeping areas, so that people are not startled, and white fire alarms for dark walls. In larger buildings, There are 2-step systems with a recorded message, which start off by stating the emergency and waiting for the security guards to be sure there is a fire, then asking for the occupants of the building to calmly evacuate. In smaller areas, there is a immediate alarm, without voice.
Fire alarms are often used in schools and other places during fire drills, or in the case of a real fire. If somebody activates a fire alarm for fun or without reason, it is called a "false alarm". Setting off a false alarm is against the law in most places.

In vitro fertilisation
"In vitro" fertilisation (IVF) is a way to let sperm fertilise egg cells outside of the womb. IVF is used so that infertile women may still have children. IVF is done by:
Louise Brown, a female born in 1978 in Manchester, England, was the first ever person to be born as a result of in vitro fertilisation.
Some religious organisations believe that adoption is a better course of action for infertile couples. They think IVF is wrong because it is unnatural.
