A ton-force is one of various units of force defined as the weight of one ton due to standard gravity. The precise definition depends on the definition of ton used.
The tonne-force (tf or tf) is equal to the weight of one tonne.
The long ton-force is equal to the weight of one long ton.
The short ton-force is equal to the weight of one short ton.

A former Honduran presidential plane is an Israel Aircraft Industries Westwind business jet, seating 7 to 10 passengers, or be reconfigured as a cargo jet. A Bell 412SP is also used as the Honduran presidential helicopter.
Since its first purchase of an IAI 1123 Westwind in 1976, the HAF Westwinds have transported the most senior government officials, both civilian and military, to many countries. The airplanes have had 3 color schemes in its history (all white in the 70s, White and Blue in the 80s, and Silver and Blue Metallic currently). The first Westwind was a 1123 model, which was later replaced by an IAI 1124 Westwind. Honduras and Panama (which has a Gulfstream IIB are the only Central American countries with presidential jet aircraft.
In the mid-70's, the Honduras government bought a package of aircraft from Israel, the first lot of 12 Dassault Super Mystères, and 2 IAI Aravas plus an IAI 1123, which had operating limitations flying out of Toncontin International Airport (TGU), on the nation's capital, Tegucigalpa, to foreign destinations such as Washington, DC, due to lack of fuel capacity. The later IAI 1124 model, acquired in the 1980s, had enhanced performance due to more powerful and fuel efficient engines.
Westwind is a 1990 novel written by Ian Rankin, and is one of the author's earliest works. The author has explained on his website that he was not happy with the outcome and unlike other early works by Rankin, it has not been reissued.
The Zephyr computer system monitors the progress of the United Kingdom's only spy satellite. When this system briefly goes offline, the book's main characters Hepton and Dreyfuss (the sole survivor of a space shuttle crash) have the only key to the enigma that must be solved if both men are to stay alive.
Rankin writes on his website that the book was an attempt at a conspiracy-theory novel, set partly in the USA (a country he had never visited) and with a lot of humour. The editor of the time did not like it, and had him make many changes - taking out the humour and the US settings and by the end he felt the book had ceased to be his. Rankin also says he doubts he could read it today.
