Question: Question: What is the current population of the city where Bricher began his career as a businessman?   Passage:Bricher was born in Portsmouth, New Hampshire. He was educated in an academy at Newburyport, Massachusetts. He began his career as a businessman in Boston, Massachusetts. When not working, he studied at the Lowell Institute.

Question: Question: What were jet fuel prices in 1975? Passage:In addition to withdrawing from the prestigious long-haul routes to New York and Los Angeles after only 18 months, other specific measures the airline took at the time to ensure its survival included dropping all scheduled flights to Belfast, Copenhagen, Gibraltar, Ibiza, Málaga, Palma de Mallorca and Tunis, indefinitely suspending scheduled services on the Glasgow—Southampton route as well as cutting the number of frequencies on the Gatwick—Glasgow and Gatwick—Edinburgh routes from six to four daily round trips. Two surplus aircraft were leased out to Air Malta and Austrian Airlines respectively for the duration of the 1975 summer timetable period. Another aircraft was stationed at West Berlin's Tegel Airport during the month of July of that year to fulfill a short-term charter contract to carry Turkish migrant workers to and from Istanbul on behalf of a local tour operator. BCal also decided to increase its 707 freighter fleet from one to four aircraft and to acquire a five-seater Piper Aztec to serve the rapidly growing executive charter market. These changes left BCal with 25 operational aircraft for the 1975 summer season. To reduce operating costs further, the airline decided to contract out its scheduled operations between Gatwick and Le Touquet to BIA. The reason for replacing BCal's One-Eleven 200 jet aircraft on this route with that airline's Herald turboprops at the beginning of the 1975 summer timetable period was the high price of jet fuel, which had made BCal's own jet aircraft operations uneconomic.
