Hello Nelson, 

Vertigo is a sensation of dizziness or loss of balance, often described as feeling like you or your surroundings are spinning or moving.
 It can be caused by a variety of factors, including inner ear problems, motion sickness, medication side effects, or neurological conditions. 
 In aviation, vertigo can be particularly dangerous as it can affect a pilot's ability to maintain control of the aircraft. Pilots can experience vertigo when their inner ear balance system becomes confused by conflicting sensory inputs, such as when flying in clouds or low visibility conditions. This can cause them to feel like the aircraft is rolling, pitching, or yawing when it is not, which can lead to disorientation and loss of control.

Phil Washington, the CEO of Denver International Airport and embattled nominee to become the next FAA Administrator, has withdrawn from consideration, U.S. Transportation Secretary Pete Buttigieg confirmed on Saturday evening. Buttigieg released a statement on Twitter saying, “The FAA needs a confirmed Administrator, and Phil Washington’s transportation and military experience made him an excellent nominee. The partisan attacks and procedural obstruction he has faced are undeserved but I respect his decision to withdraw and am grateful for his service.”

The White House initially nominated Washington to the post last July. At the time, he had been CEO of the airport for six months but brought years of transportation experience as the CEO of the Los Angeles County Metropolitan Transportation Authority and of the Denver Regional Transportation District. He also spent 24 years in the U.S. Army and led Biden’s transportation transition team after he won the presidential election.
