There are two sets of?Aerial?Challenges to?complete?in GTA 5:?Knife Flights?and?Under the Bridge.?To successfully perform Under the Bridges?you must fly an aircraft (preferably a helicopter) under certain bridges with minimal or no damage to the vehicle. Only 25 must be completed for?100% Game-Completion?and the trophy/achievement?"Career Criminal".?However, all 50 (along with all 15 Knife Flights) must be completed for the trophy/achievement?"Close Shave".

Most people use Trevor because he will likely have the highest Flying skill, which affects your?control?over the aircraft while performing Under the Bridges.

It's recommended that you use the Buzzard?for this challenge as its smaller size makes it easier to fit in small spaces where larger helicopters would likely get damaged.?Although somewhat uncommon, one can be found parked on a helipad on top of the N.O.O.S.E. Building. Your wanted-level won't raise after stealing the Buzzard from this location.

It's also recommended that you use the Quick-Save feature on your phone both before and after attempting an Under the Bridge that is particularly difficult. This will allow you to load the game in that specific location and vehicle, therefore you won't have to waste time or money if you crash. If your helicopter is damaged but hasn't crashed, you can switch to another character then immediately switch back, which will automatically repair it.
