[2] Within weeks of the agreement expiring in 1989, he announced plans for the BD-10J[2] under the aegis of Bede Jet Corporation, at the Spirit of St. Louis Airport.

The large canopy extended a fair distance above the fuselage midline, in relative terms, so twin rudders were used, one on either side, to provide clean airflow.

The aircraft was fairly conventional in construction terms, using aluminum sheeting for the majority of the airframe, and fiberglass for certain parts and fillets.

Given the engine's nominal 3,000 lbf (13 kN) thrust at sea level, the design was significantly overpowered, generally considered a major advantage for any aircraft.

However, this aircraft was significantly heavier than originally intended, the empty weight ballooning from the design 1,600 to the prototype's 2,250 lb (1,020 kg).

It was later learned that the "canopy open" indicator light could be extinguished even if the locking lugs were not in place, requiring a minor redesign to prevent this from recurring.

By 1994 three additional airframes were under construction, one by Mike Van Wagenen of Nevada, another by Jim Priebe in Ohio, and the last by Frank Everett in California.

In December 1993 Van Wagenen took over the entire BD-10 project, intending to produce completed versions of the design under the name Fox-10 and later Peregrine Falcon.

Although it had been modified to incorporate the stronger tail of Bede's design, it broke up mid-air on 30 December 1994 when the vertical stabilizers failed due to a crossflow condition, killing Van Wagenen.

The National Transportation Safety Board (NTSB) later concluded that Bede's fix was severely under-designed, and offered nowhere near the strength that had been calculated.

There appears to have been some interest on the part of the Portuguese Air Force as a replacement for its fleet of Alpha Jets in the training role,[9] but nothing ever came of this.

The investors formed Vortex Aircraft in San Diego intended to produce completed versions as the PhoenixJet for the military market, terminating Monitor's agreement due to a claimed failed payment.

It broke up in midair off the southern coast of California in 2003 after pilot Frank Everett had radioed a MAYDAY call in which he stated that the aircraft was "disintegrating".

[12] The original prototype N2BD was hangared in Scottsdale, Arizona, when the company went bankrupt, and now belongs to Fuel Fresh Inc., which operates a number of jet aircraft.

Monitor Jet's example remained in Canada, and eventually ended up in the Toronto Aerospace Museum, with its JT-15D engine stored separately.
