…information from an air traffic control radar has confirmed investigators’ fears that the military chopper was 100 feet above where it was meant to be flying at the time of the fiery crash.
The helicopter, flown by 28-year-old Captain Rebecca M. Lobach on a routine training exercise, was flying at 300 feet, but the maximum altitude permitted for choppers in the area is 200 feet.
Reagan National Airport is notoriously crowded, and the crossover in the air space between jets and helicopters is routine.
The black box data recovered from the wreckage in the Potomac River had indicated that this situation likely occurred, but the National Transport Safety Board was waiting on the air traffic control data to confirm the high altitude.
Radar data is rounded to the nearest 100 feet, which means the helicopter was flying anywhere between 251 feet and 349 feet of elevation, the NTSB said.
Meanwhile, the passenger plane was at 325 feet at the time of the crash and had been cleared to land.
The following is entirely speculative based on some pattern recognition. I am willing to change my views if shown to be wrong. One assumption is Lobach does appear to have been promoted above her experience and skill level. Call it DEI or whatever. In many of her photos she projects a cockiness that is not appropriate for someone operation dangerous machinery, including helicopters. One of her friends described her as ‘fearless’, also not good for a helicopter pilot. She had worked in the Biden admin for two years in a non-flyer capacity, so her flight skills must have been rusty. All of that could have led to the tragic crash. Overconfident, rusty, 28 years old, high on life, fearless, promoted above her actual skill level and experience, entrusted with what should have been a routine run… ABN

Totally agree with everything you said about the chopper pilot, especially considering how critically close her route would take her to commercial jets. In my opinion (and the opinion of commercial airline pilots), this frequently used chopper route flying with less than 200 foot separation between it and commercial jets (chopper max of 200 foot altitude, commercial jets at 400, but in this case likely below that) was an accident waiting to happen. I believe when ATC has multiple planes in the same airspace, they use 1000 foot separation, not 200! The chopper route needs to be shut down. Let the military take other routes across town that are not within 200 feet, or less, of commercial jets.
