A NASA research plane slid to a stop on its belly at Ellington Airport in Houston on Tuesday after its landing gear failed to deploy, sending flames across the runway, as two crew members braced inside the cockpit. Both walked away uninjured, but the incident has raised pointed questions about the reliability of aging high-altitude aircraft and the hydraulic systems that keep them airborne.
What Happened at Ellington Airport
The Martin WB-57 touched down gear-up at about 11:25 a.m. local time on Jan. 27, 2026, according to the FAA incident summary. Two people were on board. Without wheels beneath it, the aircraft scraped along the runway surface in what pilots call a belly landing, a controlled but violent maneuver that grinds the fuselage directly against pavement.
Video footage captured at the scene showed flames erupting from the underside of the plane as friction ignited sparks and debris during the slide. Emergency crews were already positioned along the runway, a standard precaution when pilots radio ahead about gear trouble. The response was immediate, though the fire was short-lived and the aircraft came to rest without breaking apart.
NASA confirmed that both occupants escaped injury and stated that a mechanical issue led to the gear failure. The agency said it would investigate the cause. No additional details about the nature of the malfunction have been released publicly, and neither crew member has been identified by name.
A Cold War Aircraft Still Flying Science Missions
The WB-57 is not a typical government plane. Originally designed in the 1950s as a tactical bomber, the Martin B-57 Canberra was later modified for high-altitude reconnaissance and atmospheric sampling. NASA operates a small fleet of these aircraft out of Ellington Airport, where they serve as platforms for scientific instruments that need to fly above most of the atmosphere. The agency’s WB-57 overview describes missions that study everything from atmospheric composition to solar eclipses, carrying sensor payloads at extreme altitudes for extended durations.
That mission profile makes the WB-57 difficult to replace. Few aircraft can match its combination of altitude, endurance, and payload flexibility. But the fleet’s age, with airframes dating back decades, means that mechanical systems including hydraulics, landing gear actuators, and structural components face the cumulative wear that comes with thousands of flight hours. A gear-up landing does not just damage the belly of the plane. It can warp the airframe, compromise wing spars, and sideline an aircraft for months or longer during repairs and inspection.
For NASA, the calculus is delicate. Retiring the WB-57s without a ready successor would leave a gap in high-altitude research capabilities. Continuing to fly them demands meticulous maintenance, aggressive inspection intervals, and a willingness to invest in refurbishing systems that were never designed to operate this long. The Ellington incident underscores how narrow that margin can be when a critical system fails at the worst possible moment.
Hydraulic Failures Are Not Isolated Events
The WB-57 incident echoes a separate gear failure that struck a FedEx 757 cargo jet, where pilots received hydraulic warnings during flight and declared an emergency. In that case, investigators found that the aircraft suffered a leak of hydraulic fluid that disabled its landing gear. Pilots on that flight requested a low pass over the tower so controllers could visually confirm the gear’s position before attempting to land. The aircraft ultimately overran the runway by about 830 feet after touching down.
The two events involve very different aircraft, one a Cold War-era research plane and the other a modern widebody freighter, but the shared failure point is telling. Hydraulic systems power landing gear extension and retraction on nearly all large aircraft. When those systems lose fluid pressure, pilots lose the ability to lower the gear through normal means. Backup systems exist, including gravity-drop mechanisms and manual cranks, but they do not always work. When every backup fails, a belly landing becomes the last option.
Most coverage of gear-up landings focuses on the dramatic visuals: sparks, flames, emergency trucks lining the runway. What gets less attention is the systemic question. Two hydraulic-related gear failures in a relatively short window suggest that maintenance protocols, fluid-line inspections, and component replacement schedules deserve closer scrutiny, particularly for specialized fleets that fly demanding mission profiles. While each case will have its own root cause, patterns in failure modes can reveal vulnerabilities that regulators and operators need to address before they lead to more serious outcomes.
What Investigators Will Look For
NASA has said it will investigate the mechanical issue, but the more consequential inquiry will likely come from federal safety investigators. The NTSB’s public database known as CAROL is where investigation dockets, preliminary reports, and safety recommendations are published as cases progress. No preliminary report on the WB-57 incident has appeared there yet, which is typical in the first days after an event.
Investigators will want to determine whether the gear failure resulted from a single component breaking, a broader hydraulic system leak, or an electrical fault in the gear-extension sequence. They will also examine maintenance records to see when the landing gear system was last inspected and whether any deferred maintenance items were pending. For an aircraft as old as the WB-57, the age of individual hydraulic lines, seals, and actuators becomes a central variable, as does any history of recurring anomalies noted by pilots or technicians.
The FedEx 757 investigation offers a template for what that process looks like. In that case, the NTSB traced the problem to a specific hydraulic fluid leak and documented the 830-foot overrun as evidence of the compromised braking that follows gear trouble. The WB-57 inquiry will follow a similar path, though the aircraft’s unique mission profile and limited fleet size may complicate the availability of replacement parts and comparative maintenance data. If investigators find evidence of fatigue, corrosion, or design limitations, they could recommend changes not only for NASA but also for any remaining operators of similar platforms.
Consequences for NASA’s Research Fleet
If the WB-57 that landed gear-up on Tuesday sustained significant structural damage, NASA could lose access to one of its few high-altitude research platforms for an extended period. The agency’s WB-57 fleet is small, and each aircraft represents a scarce capability that commercial alternatives cannot easily replicate. Grounding even one plane could delay scheduled science missions, force payload reassignments, or push back data collection timelines for atmospheric research programs.
A lengthy repair process would likely involve stripping the aircraft down to inspect load-bearing structures, replacing damaged skin panels, and evaluating whether the cost of returning the plane to service is justified by its remaining service life. For a highly modified, low-volume airframe, sourcing or fabricating replacement parts can be a project in itself. NASA must weigh those costs against the scientific value of upcoming missions that depend on the WB-57’s altitude and endurance.
The incident may also prompt a broader review of the WB-57 program. Even if the root cause is traced to a single failed component, the event highlights the operational risk of relying on a small number of aging aircraft to carry out critical research. That could accelerate discussions about life-extension programs, more extensive overhauls of hydraulic and landing gear systems, or investment in next-generation platforms that can assume some of the WB-57’s workload.
For now, the belly landing at Ellington stands as a reminder that even in carefully managed fleets, mechanical systems can and do fail. The absence of injuries speaks to the crew’s training and the effectiveness of emergency planning on the ground. The damage beneath the aircraft, still being assessed, will tell a more complicated story about the costs of keeping vintage hardware in the sky and the vigilance required to ensure that a rare research asset does not become a single point of failure for entire lines of atmospheric science.
