VTZ is the IATA code for Visakhapatnam Airport, also known as Vizag, serving the coastal city of Visakhapatnam in Andhra Pradesh. The airport has undergone significant expansion and is an important aviation hub in southeastern India. Airport codes don't always seem intuitive, but VTZ is the designated code for this facility.

GOI is the IATA airport code for Dabolim Airport, which serves Goa and is located in Vasco da Gama. Goa is a major tourist destination in India, and Vasco da Gama is the largest city in Goa. The airport is unique as it is both a civilian airport and shares facilities with a military airbase.

LKO is the IATA airport code for Chaudhary Charan Singh International Airport serving Lucknow, the capital city of Uttar Pradesh in northern India. Lucknow is known for its historical significance and cultural heritage. Airport codes like LKO are standardized identifiers used throughout the global aviation industry.

The North American X-15 was a rocket-powered aircraft that set the world record for the highest speed ever recorded by a crewed, powered aircraft (Mach 6.7). The SR-71 is the fastest air-breathing jet.

'Haben Sie einen Pass?' is German for 'Do you have a passport?'. In German, 'Pass' specifically means passport. At airports, immigration officers typically ask for your passport first before boarding passes or tickets.

Vayu Vajra is the specialized airport bus service in Bengaluru that connects Kempegowda International Airport with various points in the city. The service operates comfortable air-conditioned buses named after Vayu (wind in Sanskrit) and Vajra (diamond/thunderbolt). Vajra is the general city AC bus service.

Leh Airport (Kushok Bakula Rimpochee Airport) is the correct answer. It is situated at an elevation of 3,256 meters (10,682 feet), making it the highest civilian airport in India. Dabolim (Goa), Indira Gandhi (Delhi), and Shivaji (Mumbai) airports are all at much lower elevations in the plains or coastal regions.

The Tupolev Tu-144 is indeed the world's fastest airliner, with a top speed of Mach 2.15 (about 1,500 mph), surpassing the more famous Concorde which reached Mach 2.04. The Tu-144 was a Soviet supersonic transport aircraft that first flew in 1968, months before Concorde. Both Concorde and Tu-144 are significantly faster than subsonic airliners like Boeing 747 or Airbus A380.

The Mikoyan MiG-25 is the fastest fighter aircraft ever built, capable of reaching Mach 3.2 (about 2,190 mph). It was designed as a high-speed interceptor and reconnaissance aircraft. Modern fighters like the F-22 Raptor, while more maneuverable and advanced, have lower top speeds around Mach 2.25. The F-15 and Su-30 MKI are also slower than the MiG-25.

The SR-71 Blackbird is the fastest jet aircraft ever, with a top speed exceeding Mach 3.3 (about 2,200+ mph). While the X-15 was faster (Mach 6.7), it was rocket-powered, not a jet-powered aircraft. The SR-71 used jet engines (turbo-ramjets) and holds the record for air-breathing jet aircraft. Options like X-43A and MC-72 are either experimental or incorrect.

The Antonov An-225 Mriya was the largest aircraft ever built, with a maximum takeoff weight of 640 tonnes and a wingspan of 88.4 meters. It was designed to transport the Soviet space shuttle Buran. While destroyed in 2022 during the Ukraine conflict, it still holds the record. The Airbus A380 is the largest passenger airliner, but not the largest aircraft overall.

The X-15 rocket-powered aircraft holds the official record for the fastest manned aircraft at Mach 6.72 (4,520 mph), set by William J. Knight on October 3, 1967. While the SR-71 Blackbird is often cited as the fastest air-breathing aircraft at Mach 3.3+, the X-15 was rocket-powered and reached much higher speeds in the upper atmosphere.

The Robinson R-22 is a two-bladed, single-engine light helicopter manufactured by Robinson Helicopter Company since 1979. With over 7,000 units produced, it is the world's best-selling civilian helicopter, widely used for training and personal transportation. The Bell 206 JetRanger is also popular but has lower production numbers, while the Mi-17 is a military transport helicopter, and the AH-64 Apache is an attack helicopter.

The HAL Cheetal helicopter has the highest service ceiling among the options listed, capable of operating at very high altitudes. Service ceiling refers to the maximum altitude at which an aircraft can maintain steady level flight. The other helicopters listed have lower operational ceilings.
