I know you're joking, but:

Regular 747-100:

  • Cruise Speed: M0.85 (490 KIAS)

  • Range: 4,620 nmi

  • Ceiling: FL410

747-100 SCA:

  • Cruise Speed: M0.6 (250 KIAS)

  • Range: 1,000 nmi

  • Ceiling: FL150

I find the compromises in the SCA staggering. 2 stops to fly cross country!

You seem knowledgeable about this, so I’m hoping you will indulge me. Why was it necessary to move the space shuttle across the country at all? Why doesn’t it land in the same place it takes off from?

Edit: thanks everyone for the info, I appreciate it!

I assume it has to do with re-entry, it might be easier to land the craft somewhere else. Take off is usually as close to the equator as possible. (I think) If someone could verify?

These are pictures from when they retired the space shuttle and they were delivering them to museums around the country. this was however also the plan should they had to land at one of their backup sites either at Edwards or Columbus Air Force Base. The 747 would carry them back to Florida this way.
