This Report on Form 8-K contains forward-looking statements within the meaning

sometimes be identified by our use of forward-looking words such as "may,"
"will," "anticipate," "estimate," "expect," "project," or "intend." These
forward-looking statements reflect our plans, expectations, and beliefs and,
accordingly, are subject to certain risks and uncertainties. We cannot guarantee
that any of such forward-looking statements will be realized.

Statements regarding factors that may cause actual results to differ materially
from those contemplated by such forward-looking statements ("Cautionary
Statements") include, among others, those under the caption "Risk Factors" in
our annual report on Form 10-K for the year ended December 31, 2004, our
quarterly report on Form 10-Q for the quarter ended June 30, 2005, and our
recently filed registration statements on Form S-1. All of our subsequent
written and oral forward-looking statements (or statements that may be
attributed to us) are expressly qualified by the Cautionary Statements. You
should carefully review the risk factors described in our other filings with the
Securities and Exchange Commission (the "SEC") from time to time.

Our forward-looking statements are based on information available to us today,
and we undertake no obligation to update these statements. Our actual results
may differ significantly from the results discussed.

Item 7.01 - Regulation FD Disclosure

On October 14, 2005, a brief in support of a motion to dismiss in the case of
Highland Legacy Limited v. Steven G. Singer, et al, was filed in the Delaware
Court of Chancery, and is attached hereto as Exhibit 99.1. Motient recently
announced that it had completed an internal investigation into substantially the
same allegations that Mr. Dondero had raised in his complaint, and that
Motient's Audit Committee and their special independent counsel had found no
basis for any of his allegations. Motient's internal investigation of possible
breaches of fiduciary duties by Mr. Dondero is still ongoing. Mr. Dondero has
not cooperated with this investigation.

This information is furnished, not filed, pursuant to Regulation FD.

Item 8.01  Other Events.

On October 7, 2005, Highland Equity Focus Fund, L.P., Highland Crusader Offshore
Partners, L.P., Highland Capital Management Services, Inc. and Highland Capital
Management, L.P., each of which is a holder of Series A Preferred Stock of
Motient and is affiliated with James D. Dondero, a director of Motient, filed a
class action complaint in the Court of Chancery of the State of Delaware against
Motient Corporation and all of the directors of Motient other than Mr. Dondero,

                                       2


requesting that the court enjoin Motient's ongoing exchange offer for the Series
A Preferred Stock. The plaintiffs had initially sought expedited discovery, but
on October 12, 2005, they withdrew that request. Motient can provide no
assurance, however, that they will not reinstate such request in the future.
Motient intends to defend this litigation and believes that it is without merit.

The plaintiffs in this new lawsuit have previously brought suit against Motient
in Dallas, Texas alleging that the Series A Preferred Stock is void and seeking
rescission of their purchase of the Series A Preferred Stock. Motient views this
new lawsuit as an attempt by Mr. Dondero to prevent other holders of Series A
Preferred Stock who wish to participate in the exchange offer from doing so.
