Why the 90-second transition from hover to forward flight is the hardest problem in the eVTOL air taxi industry.
VectorReliable Robotics flew an empty Cessna Caravan by automating the pilot's job - not building a new aircraft - betting cargo leads aviation's autonomous future.
VectorHow Sierra Space's Dream Chaser spaceplane returns from orbit at just 1.5 g and lands on a runway like an airliner.
VectorRadio Hangar explores The Stormscope, Sferics, and How a Box on Your Panel Maps Lightning Without Ever Painting a Cloud.
VectorWhy US ADS-B runs on two frequencies, how ADS-R stitches them together, and why a receive-only box hides traffic from you.
VectorHow Aireon's 66 satellites brought real-time ADS-B surveillance to the oceans and are shrinking separation over the North Atlantic.
VectorWhy Beta Technologies skipped the tilt-rotor for a simpler lift-plus-cruise eVTOL design, and what that bet means for certification and pilots.

VectorThe NEXRAD radar image on your tablet can be 15-20 minutes older than its timestamp shows - here's why, and how to use it safely.
VectorHow Regent Craft's electric Viceroy seaglider uses wing-in-ground effect and fly-by-wire to make a 60-year-old idea finally flyable.
VectorHow TCAS prevents midair collisions, the fatal night over Lake Constance, and the absolute rule pilots learned: fly the box.
VectorHow Auto-GCAS, the Automatic Ground Collision Avoidance System, takes control from an unconscious pilot to pull an F-16 off the ground and save lives.
VectorElectra's hybrid-electric EL9 Ultra Short uses century-old blown lift and eight electric motors to take off in about 150 feet.
VectorJoby's S4 air taxi is deep in FAA certification, but the paperwork - not the flying - decides when you'll actually ride one.
VectorInside Stratolaunch's Roc, the widest airplane ever built, and how it became a reusable runway in the sky for hypersonic flight testing.
VectorCFM's RISE open fan ditches the engine cowling to cut fuel burn 20%, betting the ducted turbofan has hit its efficiency ceiling.
VectorThe Pipistrel Velis Electro became the first type-certified electric airplane in June 2020, making battery-powered flight training legal.
VectorHow ADS-B made every aircraft trackable in the clear - and how LADD and the Privacy ICAO Address let some pilots disappear.
