Nicotine is a nicotinic acetylcholine receptor (nAChR) agonist, (a Naâº/Kâº ionophore through neural postsynaptic membranes in mammals and insects) except at nAChRÎ±9 and nAChRÎ±10 where it acts as an antagonist.

All 150 on board are believed to have been killed. The aircraft in question was 24 years old and originally flown by Germanwingsâ parent company, Lufthansa. Germanwings is a low-budget subsidiary of Lufthansa. While the average age of a U.S. domestic commercial airliner is 11 years old, it is not uncommon for aircraft to still be in service at 24, 25, even 30 years old. âTwenty-four is not terribly old for an aircraft,â Bill de Decker, chairman of Texas-based Conklin & de Decker Aviation, told TravelPulse this morning.
Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled. The Wright brothers invented and flew the first airplane in 1903, recognized as the first sustained and controlled heavier-than-air powered flight.
