Significant Accounting Policies [Text Block]	2. Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements and the related notes (the “Financial Statements”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission. These Financial Statements include the accounts of the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain historical amounts have been reclassified to conform to the current year’s presentation, including salaries, wages, and benefits associated with operations personnel employed at the Company's hangar development sites. $193 of amounts previously classified within general and administrative expenses on the consolidated statement of operations for the year ended December 31, 2021 no no Notwithstanding the legal form of the Yellowstone Transaction pursuant to the terms therein, the Yellowstone Transaction was accounted for as a reverse recapitalization in accordance with GAAP (the “Reverse Recapitalization”). Under this method of accounting, Yellowstone was treated as the acquired company for financial reporting purposes, and Sky was treated as the accounting acquirer. In accordance with this accounting method, the Yellowstone Transaction was treated as the equivalent of Sky issuing stock for the net assets of Yellowstone, accompanied by a recapitalization. Sky was deemed the accounting acquirer for purposes of the Yellowstone Transaction based on an evaluation of the following facts and circumstances: • The LLC Interests, through their ownership of the Class B Common Stock, hold a majority voting interest in the Company; • The LLC Interests have the ability to nominate and elect the majority of the Company’s Board of Directors; • Sky’s senior management team comprises the senior management of the Company; and • Sky’s assets were larger in relative size compared to Yellowstone’s assets prior to the Yellowstone Transaction. Thus, the financial statements included in this annual report for the year ended December 31, 2022 no Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include assumptions used within impairment analyses, estimated useful lives of depreciable assets and amortizable costs, estimates of inputs utilized in determining incentive compensation expense and financial instruments such as warrants, and estimates and assumptions related to right-of-use assets and operating lease liabilities. Actual results could differ materially from those estimates. Risks and Uncertainties The Company’s operations have been limited to-date. For most of its history, the Company was engaged in securing access to land through ground leases, and developing and constructing aviation hangars. The major risks faced by the Company is its future ability to obtain additional tenants for the facilities that it constructs, and to contract with such tenants for rental income in an amount that is sufficient to meet the Company’s financial obligations, including increasing construction costs due to inflation.

Unrealized gains and losses are excluded from earnings and are reported as a component of comprehensive income (loss). The Company periodically evaluates whether declines in fair values of its available-for-sale securities below their book value are other-than-temporary. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss as well as the Company's ability and intent to hold the available-for-sale security until a forecasted recovery occurs or its contractual maturity. Additionally, the Company assesses whether it has plans to sell the security or it is more likely than not December 31, 2022 2021, Restricted Investments Held-to-Maturity Pursuant to provisions within the Master Indenture of the Series 2021 8, The Company has the ability and intent to hold these restricted investments until maturity, and as a result, the Company would not December 31, 2022 one one five Cost of Construction Cost of construction on the consolidated balance sheets is carried at cost.

Costs are capitalized once the construction of a specific capital project is probable. Construction labor and other direct costs of construction are capitalized. Professional fees for engineering, procurement, consulting, and other soft costs that are directly identifiable with the project and are considered an incremental direct cost are capitalized. The Company allocates a portion of its internal salaries to both capitalized cost of construction and to general and administrative expense based on the percentage of time certain employees worked in the related areas.

Other long-lived assets Long-lived assets on the consolidated balance sheets consists principally of ground support equipment, software, and computer equipment. Long-lived assets are carried at cost less accumulated depreciation. Maintenance and repair expenses are charged to expense as incurred.
