On that point, I've been thinking of doing some math for a while now. For the sake of argument, lets assume NMUSAF fully assembles and displays all of the aircraft in the hangar. Further, lets assume that none of the aircraft overlap and that each aircraft is represented by a square formed from lines drawn from the nose, tail and each wingtip. (Yes, some could fit underneath the wings of the others and aircraft are not really squares, but calculating that would take a lot more effort.)
Airframe - Length x Wingspan = Area- AQM-34Q - 21 ft 11 in x 12 ft 11 in (BQM-34A) = 283 sq ft
- AQM-60 - 38 ft 1 in x 9 ft 10 in = 374 sq ft
- B-23A - 58 ft 4 in x 92 ft 0 in = 5,637 sq ft
- C-21A - 48 ft 8 in x 39 ft 6 in (Learjet 36A) = 1,922 sq ft
- C-39 - 61 ft 11 in x 85 ft 0 in (DC-2) = 5,263 sq ft
- CASA 2.111H - 53 ft 10 in x 73 ft 10 in = 3,975 sq ft
- CASA 352L - 96 ft x 18 ft 2 in (Ju 52) = 1,744 sq ft
- CH-21B - 52 ft 6 in x 15 ft 9 in (CH-21C) = 826 sq ft
- EF-111A - 76 ft 0 in x 32 ft 0 in (swept) = 2,432 sq ft
- F-107A - 61 ft 10 in x 36 ft 7 in = 2,262 sq ft
- Fi 156 C-1 - 32 ft 6 in x 46 ft 9 in = 1,519 sq ft
- GAM-63 - 31 ft 11 in x 16 ft 8 in = 531 sq ft
- H-5 - 57 ft 1 in x 13 ft 0 in = 742 sq ft
- La-17M - 27 ft 9 in x 24 ft 7 in = 682 sq ft
- MiG-25RB - 78 ft 2 in x 46 ft 0 in (MiG-25PD) = 3,596 sq ft
- NF-16A - 49 ft 5 in x 32 ft 8 in (F-16C) = 1,614 sq ft
- NT-33A - 37 ft 9 in x 38 ft 10 in (T-33A) = 1,466 sq ft
- RB-34 - 51 ft 5 in x 65 ft 6 in = 3,368 sq ft
- S‐51 - 57 ft 1 in x 13 ft 0 in = 742 sq ft
- Su-22M - 62 ft 5 in x 33 ft (Su-17M4, swept) = 2,060 sq ft
- T-33A - 37 ft 9 in x 38 ft 10 in = 1,466 sq ft
- T-46 - 29 ft 6 in x 38 ft 7 in = 1,138 sq ft
- T-6G - 29 ft x 42 ft = 1,218 sq ft
- TG-3 - 27 ft 7 in x 54 ft 0 in = 1,490 sq ft
- X-19 - 44 ft 5 in x 23 ft 6 in (rear wing) = 1,044 sq ft
- XF-91 - 46 ft 9 in x 31 ft 2 in = 1,457 sq ft
- YF-4E - 63 ft 0 in x 38 ft 5 in (F-4E) = 2,420 sq ft
- YQM-98 - 38 ft 4 in x 81 ft 2 in = 3,111 sq ft
- YRF-84 - 38 ft 1 in x 36 ft 5 in (F-84G) = 1,387 sq ft
This gives a total of 55,499 square feet of floor space. Now, let's not forget, they have a B-17D and F-15 in restoration:
Airframe - Length x Wingspan = Area- B-17D - 74 ft 4 in x 103 ft 9 in (B-17G) = 7,712 sq ft
- F-15 - 63 ft 9 in x 42 ft 10 in (F-15C) = 2,731 sq ft
These add another 10,443 square feet to bring the total to 65,942 square feet of floor space. However, we haven't even touched the big ones yet. They also have a C-17, KC-135, just received a KC-10 today and presumably will be receiving a C-5 and VC-25 at some point in the future:
Airframe - Length x Wingspan = Area- C-5 - 247 ft 1 in x 222 ft 9 in = 55,038 sq ft
- C-17 - 174 ft x 169 ft 9 in = 29,537 sq ft
- KC-135 - 136 ft 3 in x 130 ft 10 in = 17,826 sq ft
- KC-10 - 181 ft 7 in x 165 ft 4.5 in = 30,029 sq ft
- VC-25 - 231 ft 10 in x 196 ft 8 in = 45,594 sq ft
Together, these five airframes are nearly triple the amount of floor space everything else listed so far: 178,024 square feet. The grand total to bring everything into hangars at the main facility is then a whopping 243,966 square feet of floor space! The fourth hangar encompasses 224,000 square feet. So the museum needs at least one more hangar of the same size to fit the rest of their current and near future collection.
So, when people ask, why are these aircraft not on display, consider the number 243,966 square feet.
